  • Removal Of Lead And Cadmium Ions From Aqueous Solution Using Vigna
           subterrenea Seed Shells Carbon

    • Free pre-print version: Loading...

      Authors: K O Ijege, E E Jasper, V A Rwuaan
      Pages: 1 - 14
      Abstract: Carbon derived from Vigna subterrenea seed shells (CVSS) was employed for the effective removal of Pb (II) and Cd (II) by adsorption. CVSS was prepared via the chemical activation method using the nitric acid solution as activating agent. The effects of operational parameters such as pH, adsorbent dosage and contact time were studied. Adsorption isotherms and kinetics experiments were performed at 25 oC and 30 oC. The metal ions uptake increases with an increase in solution pH for the carbon for both Pb (II) and Cd (II) ions. Across the temperatures, equilibrium removal efficiencies of CVSS for Pb (II) and Cd (II) were 89.77≤ and≤ 73.81) respectively. Maximum adsorption capacity Qmax of CVSS for Pb (II) and Cd (II) were 9.25 and 8.56mg/g respectively. Langmuir's model provides the best fit for both lead and cadmium. Adsorption kinetics obeyed the pseudo-second-order model.

  • Smoke Toxicity Of Some Firewood Samples Used In Anambra State.

      Authors: C O Ifediora, T U Onuegbu
      Pages: 15 - 24
      Abstract: The toxicity of smoke from firewood samples to its users has been investigated. The aim of this research is to evaluate the smoke toxicity of selected firewood samples from Umuoji, in Idemili North Local Government Area of Anambra State. The components of the smoke samples were analyzed using a flue gas analyzer; Testo 350XL, the gases emitted while burning these woods were identified. The wood ashes were digested using APHA standard methods and analyzed using Agilent A200 series Atomic Adsorption Spectrophotometer. From the findings of the study, the result of the analysis shows that wood smoke is made up of VOC/Hydrocarbons (2134ppm – 27340ppm), oxides of Sulphur (2ppm – 54ppm), Carbon monoxide (28ppm – 956ppm), Carbon dioxide (20.59ppm – 20.80ppm), oxides of Nitrogen (0.1ppm – 0.8ppm) and Hydrogen gas (18ppm -100ppm) in proportions higher than the threshold limit values (TLV) acceptable by the world health bodies, except for the oxides of nitrogen which shows danger only in the inhalation of N2O4 while the heavy metal analysis of their wood ash showed presence of Lead (0.19ppm – 1.19ppm), Zinc (7.51ppm – 14.60ppm), Copper (0.89ppm – 2.36ppm), Chromium (0.35ppm – 0.58ppm) and Cadmium (0.15ppm – 0.58ppm) whose proportions are higher than the threshold limit values (TLV) acceptable by the world health bodies. Data obtained in this study were subjected to descriptive statistical analysis using ANOVA and by Friedman non – parametric statistical test. The best wood in relation to smoke toxicity are Acacia, Gmelina, and African bread fruit and are recommended for wood fuel, while Bamboo, Avocado, and African star apple should be rarely used. In relation to heavy metal content, Gmelina, African star apple and Bamboo woods are preferred to the other wood samples.

  • The Study of Phytochemicals, Proximate and Mineral Contents of Sweet
           Orange Seeds and Peels.

      Authors: D Uzama, S C Okolo, A B Adebiyi, R U Okoh-Esene, A T Orishadipe
      Pages: 25 - 32
      Abstract:  The study of phytochemicals, proximate and mineral contents of sweet orange seeds and peels was carried out. Standard methods were adopted in carrying out the phytochemical and proximate analyses. Atomic Absorption Spectrophotometer was employed for the mineral composition. The phytochemical analysis revealed the presence of alkaloids, saponins, flavonoids,  terpenoids, tannins, phenols, glycosides, volatile oils and steroids in both the seeds and peels of the sweet orange .The proximate analysis revealed that the seeds contain moisture(10.92%), ash(4.31%), crude fat(6.37%), crude fibre(1.67%), crude protein(2.36%), and carbohydrate(74.37%) while the peels contains moisture(10.43%), ash(3.66%),crude fat(4.83%),crude fibre (2.35%),crude protein(2.17%) and carbohydrate(76.56%)..The mineral analysis revealed that the seeds contain Mn (0.13mg/100g), Cu(0.27mg/100g), Ni(0.03mg/100g), Cd(0.04mg/100g), Cr(0.15mg/100g), Zn(0.63mg/100g), Ca(31.00mg/100g), Mg(1.02mg/100g), Na(55.56mg/100g) and K(57.50mg/100g) while the peels contain Mn(0.13mg/100g), Cu(0.10mg/100g), Ni(0.01mg/100g), Cd(0.04mg/100g), Cr(0.60mg/100g), Zn(0.27mg/100g), Ca(133.73mg/100g), Mg(0.13mg/100g), Na(55.56mg/100g), and K(60.00mg/100g).The seeds and peels of sweet orange can serve as potential source of nutrients and drugs, with the seeds being better preferred than the peels.

  • Synthesis And Biological Studies Of A Tripodal Schiff Base Derived From
           1,3,5-Tribromomethylbenzene And Its Trinuclear Ce(IV) and Nd(III) Salen
           Capped Complexes

      Pages: 33 - 55
      Abstract: A tripodal Schiff base ligand, 1,3,5-tris(4-(4-carboxyphenyliminomethyl) phenoxy methyl) benzene (TT) was synthesized in a two-step reaction involving 1, 3, 5-tribromomethylbenzene. The ligand was used to synthesize Ce(IV) and Nd(III) salen capped complexes. These compounds were characterized using UV-Visible, IR, 1H, and 13C NMR spectroscopies, elemental analysis, and molar conductivity measurements. The spectral studies indicate that the ligand is hexadentate and coordinates to the Ce(IV)and Nd(III) ions through the oxygen atoms of the carboxylic group. The trinuclear Ce(IV) and Nd(III) salen capped complexes were characterized as being bridged by carboxylate anions to the Ce(IV)and Nd(III) salen centers and displays a coordination number of eight by involving two hydroxyl groups in the coordination sphere. The in vitro antimicrobial activities of the ligand and complexes were investigated against Gram-negative bacteria: Escherichia coli (ATCC 6749) and Pseudomonas aeruginosa (ATCC 9027), Gram-positive bacteria: Staphylococcus aureus (ATCC 6538P) and Bacillus cereus (ATCC 14579), and fungi: Candida albicans and Aspergillus niger by the agar well diffusion technique. In vitro antimicrobial test indicate that [{Nd(OH)2(salen)}3(TT)].3H2O is more potent against the test microorganisms relative to TT and [{Ce(OH)2(salen)}3(TT)].3H2O.
