摘要：

This work presents experimental results obtained in the process of phenol and Fastac pesticide removal from aqueous solutions using batch technique (immobile phases, 3D shaker, magnetic stirring) on Romanian bentonites (Orasul Nou and Petresti deposits). Bentonite samples were used in suspension and immobilized in alginate beads. Influences of bentonite provenience and quantity, batch contact type and phenol concentration over the process efficiency were studied. The most effective bentonite proved to be the one from Orasul Nou. Removal efficiencies up to 80% were reached in case of phenol solutions with concentrations smaller then 50 mg/L on immobilized bentonite and Fastac (100 mg/L) on suspended bentonite. Also, adsorption capacity increased with the decrease of the bentonite quantity and the increase of the initial phenol concentration.
