  • Treatment of Syrian Phosphogypsum using Acids and Bases

    • Authors: Mohammad Nour Alkheder
      Abstract: Phosphogypsum is a technologically enhanced naturally occurring radioactive material (TE-NORM) that contains radionuclides from 238U and 232Th decay series which are of most radio-toxicity. The reduction in concentration of radionuclides content from PG was based on leaching of 226Ra, 210Pb, U and 40K using different chemicals.The factors which affect the leaching process such as leaching reagent, concentration of the proposed reagent, liquid-solid ratio, contact time, temperature and multi leaching effect were optimized. Based on the experimental results, about 79.4%, 57.9%, 65.7% and 89.8% of U, 226Ra, 210Pb and 40K respectively, were successfully removed from the PG under optimum conditions ( HNO3, concentration (4M), liquid-solid ratio mL-gr(1-1), contact time (2h), temperature (60°C) and three leaching steps). Using this treatment of PG waste leads to obtain a decontaminated product that can be safely used in many industrial applications. Keywords: Phosphogypsum waste, Leaching process, Radioactive materials, TENORM.

  • Physico-chemical Parameters and Heavy Metals Determination in Selected
           Medicinal Plants Sold in ‘Yar Marina Market, Sokoto-Nigeria

    • Authors: Uba; A., Baburo, S.I.B
      Abstract: The increasing prevalence of environmental pollution, especially soil contamination by heavy metals has led to their increased uptake in the human food chains through plant parts. Accumulation and magnification of heavy metals and other toxins in human tissues through consumption of herbal remedies can cause serious negative impacts on health. This study was aimed at determining the physico-chemical parameters and the levels of heavy metals (Cr, Cd, Mn, Cu, Fe, Pb, Zn and Ni) concentration in selected crude herbal plants sold in ‘Yar Marina’ Market, Sokoto-Nigeria. The physico-chemical parameters were determined using standard analytical methods and the heavy metals were determined using Atomic Absorption Spectrophotometry (AAS) after wet digestion. The results shows that moisture content is 3.67 – 4.83 %,, ash value 11.0 – 18.7 % and acid insoluble ash 1.0% 8.4 %. The result also revealed the maximum concentrations (mg/Kg) of the heavy metals in the samples as: 0.034±0.001, 14.977±0.001, 0.193±0.001, 15.160±0.002, 1.715±0.001, 0.335±0.001, 0.429±0.001 for Cd, Mn, Cu, Fe, Pb, Zn and Ni respectively. While the moisture content of the samples was excellent, ash and acid insoluble ash suggested some level of contermination probably with sand. Also, the levels of all the heavy metals analysed in the samples were found to be of acceptable limits for heavy metals in plant samples. The exception was only for manganese in Cassia singueana and Combretum micranthum leaves.. It is therefore, suggested that the quality, safety and efficacy of these medicinal plants be improved through pharmacovigilance. Keywords: Heavy Metals, Medicinal Plants, Physico-chemical and ’Yar Marina market.

  • A Review of Bio-tanning Materials for Processing of Fish Skin into Leather

    • Authors: Ramesh Duraisamy Seguye Shamena
      Abstract: Leather is a durable and flexible material created by the tanning of animal raw hide and skin, primarily cattle hide and natural grain, variation in the grains, good breathability and other natural features are all signs that the material is genuine. The most commonly used tanning methods are chrome and vegetable tanning. The bio-tanning of hide/skin refers to tanning of hide or skin by employing vegetables, animals especially brain and microorganism (enzyme) to produce leather as it is considered as the "green tanning agent" because of its biodegradation and environmental friendly as well as can easily be applied for various sorts of leather. The vegetable tannins are extracted by using a suitable solvent, usually water followed by concentration and spray drying to get powder or solid. The production of fish skin leather is based on taking waste and turning it into a useful product and due to similarity in strength to tough cow hide, can be used for anything from handbags, belts, clothing, small accessories and shoes, furniture, interior decoration, etc. Keywords: leather, bio-tanning, tannins, fish skin, spray drying, vacuum drying, tilapia fish

  • Studying Effect of Mg Doping on the Structural Properties of Tin Oxide
           Thin Films Deposited by the Spray Pyrolysis Technique

    • Authors: Abdul Rahman Sakhta
      Abstract: Mg doped tin oxide transparent conducting thin films were deposited at a substrate temperature of 450°C by spray pyrolysis method. Structural properties of the films were investigated as a function of various Mg-doping levels from 0 to 9wt% while all other deposition parameters such as substrate temperature, spray rate, carrier gas pressure and distance between spray nozzle to substrate were kept constant. The results of x-ray diffraction have shown that the deposited films are polycrystalline structure in tetragonal phase with preferential orientations along the (101), (301), and (211) planes. The relative intensities, distance between crystalline planes (d), crystallite size (D), dislocation density (ẟ) and lattice parameters (a), (c) were determined. The variations of the surface morphology have been studied by Scanning Electron Microscope (SEM). Keywords: Thin films, Magnesium doped Tin Oxide, Spray pyrolysis, Structural properties, Scanning electron microscope.
