    Abstract: This paper reports on the catalytic behaviour of cyanocobalamin (VB12) towards the reduction of polyhalogenated organic pollutant 2, 2, 2–trichloro-1,1-bis (4-chlorophenyl) ethanol (dicofol) in acetonitrile-aqueous solution containing 0.1M KNO3 supporting electrolyte. Dicofol is a persistent, toxic organochlorine acaricide used in agriculture and h... Show More

    Abstract: Copolymerization of acrylic acid (AA) and /or glycidyl methacrylate (GMA) with silk was carried out using H2O2/Cu2+reduced system. The results revealed that increasing H2O2 concentrations enhance polymerization up to 0.078 meq/l and also decreased the (TC) and (GY). Presences of Cu+2 ions up to 5 mmol/l accelerate the polymerization of (GY), (GE) a... Show More
