Abstract

Imazapyr sorption on a macroporous mesoporous natural phosphate rock

Author(s): M. Flayou and S. El Hajjaji

The removal of imazapyr pesticide from aqueous solutions, using amacroporous natural phosphate rock (PR)as adsorbent, is studied. The adsorption equilibrium, isotherms and kinetics for imazapyr are studied and the data was fitted into various mathematical models and Langmuir and Freundlich isotherms. Experiments performed by the batch method showed that the sorption process occurs by a monolayer deposition of imazapyr pesticide according to a second order reaction
