the structural and electrical properties of polyaniline-cobalt sulphate nanocomposite prepared by chemical method.polyaniline-cobalt sulphate nanocomposites were synthesized by the cobalt sulphate and ammonium persulphate and aniline.this paper reports on chemical technique using for synthesis of cobalt nanoparticles in the composite bridge is aniline. electrical conductivity of polyaniline wit...

The extraction of metals from supports based on calcium phosphate was investigated; we conducted experiments with metal solutions at various concentrations, and using two carriers’ calcium phosphate hydroxyapatite and hydroxyapatite in the presence of polyethylene glycol polymer. The results show a metal retention of selectivity with excellent yields. The kinetic study shows that the extraction...

In this work, separation of cobalt(II) over lithium(I) ions from aqueous chloride solutions by synergistic solvent extraction (SX) has been studied. A synergistic mixture of commercial extractants such as bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272) and tributyl phosphate (TBP) in kerosene was used as a selective extractant. The investigations were first performed to select optimal co...

Intensified solvometallurgical process by combining solvoleaching and solvent extraction to recover cobalt from lithium oxide, in presence of current collectors aluminium copper.

Cadmium is an extremely toxic metal, which even in low levels is harmful to the human body, animals and also plants. Human manufactures such as cadmium-nickel batteries and pesticides, plastic, make the earth polluted with cadmium; therefore removal of the cadmium Water is vital for human and animal. Scientists use different methods for cadmium removal including adsorption, precipitation, i...

BACKGROUND Cobalt is one of the most important constituent present in ceramic industries. Glazers are the relevant workers when they are producing blue colored ceramic, causing occupational exposure to such metal. Through this study, urinary cobalt was determined in glazers in a ceramic industry when they were producing blue-colored ceramic glazes. METHODS In this case-control study, spot uri...
