SORPTION OF APOLAR PESTICIDES BY UNITS OF BENZOIC ACID PROPYL ESTER IN CYCLIC PHOSPHAZENE

ABSTRACT The effects of temperature, pH and agitation time (equilibrium) on the adsorption process of different pesticides on N3P3(OC6H4COOCH2CH2CH3)6 was studied. With optimal conditions experimental, the adsorption isotherms have been realized with through Langmuir and Freundlich models. Pesticide...
