  • Tinidazol antibiotic degradation in aqueous solution by zero valent iron
           nanoparticles and hydrogen peroxide in the presence of ultrasound
    • Abstract: Abstract The purpose of this study was to investigate the efficiency removal of the antibiotic Tinidazol by hybrid system of ultrasonic/nZVI/H2O2 (US/nZVI/H2O2) in aquatic environment. It examined the effect of variables such as concentration of antibiotic, nZVI and H2O2, frequency of US and pH. Also the performance of system in removal of COD and electrical energy consumed by the ultrasonic bath was investigated. Findings showed the best efficiency (93%) for system in pH 3, concentration hydrogen peroxide of 1M, amount of 0.2 g of zero valent iron nanoparticles and 130 kHz radiation frequency. According to the results US/nZVI/H2O2 method can be good performance in removal of antibiotics Tinidazol and similar pollutants.

  • Study of the sorption of synthetic dyes from aqueous solution onto
           cellulosic modified polymer
    • Abstract: Abstract The ability of cyclodextrins to facilitate inclusion of chemical molecules can be exploited to obtain new adsorbent materials for organic pollutants removal such as synthetic dyes from wastewater. In this work we report a study on the formation of the complex acrylamidomethylated-β-cyclodextrin, then on the grafting on cellulosic polymer. The grafting is initiated by ceric ions Ce (IV) and confirmed by infrared analysis (FTIR). Scanning electron microscopy (SEM) analysis was carried out to evaluate properties of structure and surface of grafted polymers. The experiments of balance adsorption of reactive, acid, and cationic dyes were made in aqueous solutions for 24 h at pH: 3, 6 and 11. Our results indicate formation of a permanent chemical bond between β-cyclodextrin and polymer materials. The cellulosic polymers can effectively be modified without significant change in the structural properties. In addition, absorption tests showed that the grafted functions clearly improve retention of liquids by cellulose. The results of dye adsorption in aqueous medium show the ability of modified polymer to fix organic dyes, and to be used in the industrial liquid waste processing. Differences in adsorption capacities may be due to the effect of dye structure.

  • Removal of Cr(VI) from aqueous solutions by calcined Zn/Al- and
    • Abstract: Abstract The paper has investigated sorption of Cr(VI) from aqueous solutions by calcined forms of Zn/Al- and Mg/Fe-hydrotalcites. We have determined the impact of sulfate-, hydrocarbonate- and nitrate-ions on the degree of removal of Cr(VI) from aqueous solutions. The most effective removal of chromate-ions from aqueous solution by calcined forms of hydrotalcites is observed in an acid and weakly acid region of the pH: at an increase of the pH from 4 to 8 the adsorption values decrease by ∼ 6–7%.

  • Membrane treatment of wastewater obtained after the whey processing
    • Abstract: Abstract The separation of model solutions of whey nanofiltration permeate, which is a wastewater at the majority of enterprises, has been investigated using the techniques of low-pressure reverse osmosis and electrodialysis. A process flow diagram for the treatment of such wastewater is proposed. Electrodialysis enabling us to remove up to 80% of mineral salts is recommended with subsequent concentration of diluate by using the low-pressure reverse osmosis. The possible uses of resultant solutions are also described.

  • Water treatment of brilliant green using the modified ceramic
           microfiltration membranes
    • Abstract: Abstract High efficiency of the water treatment of the cationic dye (brilliant green) by using domestic ceramic microfiltration tubular membranes modified by clay mineral has been shown. The highest dye retention coefficient (99.9%) in water by such membrane was observed during the water treatment at the initial brilliant green concentration of up to 30.0 mg/dm3 under the working pressure of 0.5 MPa. In these conditions the specific capacity of membrane amounted to 0.07 m3/(m2 h).

  • Influence of the concentration of fluorine ions and clayey particles on
           the efficiency of aluminum coagulants in defluorination of water
    • Abstract: Abstract The paper has investigated the influence of the initial concentration of fluorine ions (2.0–8.5 mg/dm3) on the efficiency of sulfate (SA), basic sulfate (OSA 2.0) and basic aluminum chloride (5/6 OXA) in defluorination of water. It has been established that replacement of aluminum sulfate by its basic salts makes it possible not only to reduce consumption of the coagulant, but also provides a possibility to clean waters polluted with fluorine ions by 27–35% without additional introduction of alkaline agents. The paper has shown good promises in using OSA 2.0 for defluorination of low turbidity waters (underground sources), while 5/6 OXA—for water with relatively high contents of suspended impurities.

  • Removal of arsenic compounds from natural waters using a hybrid system
           (photocatalysis-reverse osmosis)
    • Abstract: Abstract The extraction process of As(III) and As(V) compounds from water using the reverse osmosis treatment with membrane ESPA-1 has been studied. The retention coefficient of As(III) was shown to amount to 47–56% in pH interval of 5.2–9.4; as a result, the arsenic concentration in permeate exceeds the drinking water MAC by about 5 times. A hybrid system (photocatalysis-reverse osmosis treatment) was proposed for the effective removal of arsenic compounds from natural waters.

  • Highly-effective liquid chromatographic determination of
           2,4,6-trinitrophenol in surface waters after its selective solid phase
    • Abstract: Abstract The paper has proposed a new adsorbent for solid-phase extraction concentration of 2,4,6-trinitriphenol from aqueous objects of the environment followed by its determination in the concentrate by the method of highly performance liquid chromatography (HPLC). Silica modified by N-epoxypropylcarbazol was used as solid-phase extragent, which in the pH 1.5 ± 2.5 interval extracts up to 98% of the matter being analyzed. Sorbent capacity in terms of 2,4,6-trinitrophenol in the Henry area constitutes 5.3 mg/g, distribution coefficients reach values 7.9 × 104 cm3/g. Nitrophenols are quantitatively eluted in dimethyl sulfoxide, which makes it possible to determine them by the HPLC with a diode array detector at the level 18 μ/dm3.

  • Development of the zeolite-sorption process for electroplating wastewater
    • Abstract: Abstract Regularities of the sorption of heavy metal ions on the natural zeolite (calcium heulandite) have been investigated. Relationships of the sorption of heavy metal ions as a function of the fraction size of test zeolites were obtained. The sorption values in static conditions for nickel, copper and zinc ions amounted to 5.9, 4.8 and 2.7 mg/g, respectively, making it possible to use zeolites as sorbents in the treatment of wastewater from electroplating facilities. The degree of wastewater purification in a filter with calcium heulandite medium amounted to ∼ 90%.

  • Detection of heterogeneities of water medium
    • Abstract: Abstract The paper has experimentally investigated changes of the dimensional spectrum and concentrations of optical heterogeneities of waters having different content of deuterium under the effects of laser radiation. It has been found out that low intensity laser radiation (1 mw/cm2) did not affect qualitative and quantitative characteristics of optical heterogeneities whereas an increase of the density of laser radiation flow power to 8 W/cm2 results in an increase of their relative amount: for light, distilled, and heavy waters—respectively 45; 30 and 15%. The changes of the dimensional spectrum of optical heterogeneities have identical principle—an increase of the content of small structures and a decrease in the content of large ones.

  • Raising the efficiency of coagulation treatment of the Dnieper River water
    • Abstract: Abstract The article has investigated the possibility of raising the efficiency of coagulation treatment of the water of the Dnieper river without an increase of the dose of the coagulant. Paper showed synergism of the combination of preliminary ozonization and coagulation at a fixed coagulant dose. The use of ozone doses within the range 2.9–3.6 mg/dm3 is most expedient in summer months, when the content of the total organic carbon in the water increases. An increase of the fraction of biologically accessible carbon with such doses is not observed.

  • Iodometric solidphase spectrophotometric determination of nitrite with the
           use of polyurethane foam as a sorbent
    • Abstract: Abstract The article contains the developed technique of iodometric solidphase spectrophotometric determination of nitrite in natural water using polyurethane foam as a sorbent. The redox reaction between nitrite and iodide, sorption of formed iodine by polyurethane foam and its detection on the surface of the sorbent lie behind the technique. Linearity of the graduation graph is observed until the nitrite concentration up to 0.5 mg/dm3, the detection limit is 0.006 mg/dm3 at the sample volume 10 cm3.
