Adsorption of the herbicide diuron and its three degradation products: 3-(3,4-dichlorophenyl)-1-methylurea, 1-(3,4-dichlorophenyl) urea and 2,4-dichloroanilin on three organo–inorgano-clay minerals, was investigated. These surfactant-modified pillared clays (SMPC) were prepared by intercalation of polycations of aluminum(III), iron(III) or titanium(IV) into the interlamellar space of a montmorillonite,...
Adsorption of pesticides ametryn, aldicarb, dinoseb and diuron from aqueous solution onto high specific area activated carbon-cloth was studied. Kinetics of adsorption was followed by in situ UV-spectroscopy and the data were treated according to various rate models. The extent of adsorption was determined at the end of 125min adsorption period. Rate constants and the extent of adsorption for the...
