The utility of activated charcoal for the removal of malathion from saline waters has been explored. The adsorption capacity of charcoal for malathion has been found to be 117 mg g-1. Adsorption follows the Freundlich adsorption isotherms, the value of k and 1/n for charcoal being 1.6 and 0.60, respectively. Malathion can be eluted with methanol or(More)
The influence of organic matter, calcium carbonate, flyash, saline and alkaline salts, inorganic fertilizers, surfactants, and exchangeable ions on the mobility of different phosphorus pesticides has been studied using soil thin-layer chromatographic techniques. The variations in Rf, RB, and RM values of DDVP, diazinon, Ekatin, Folithion, malathion,(More)
The influence of pH, leachates of alkaline and saline salts, inorganic fertilizers, and surfactants on the movement of eight organophosphorus pesticides, viz., DDVP, diazinon, Ekatin, Folithion, malathion, metasystox, parathion methyl, and Rogor has been studied using soil thin layer chromatographic techniques. The variation in the movement of pesticides(More)
