有机改性膨润土对氧化乐果的吸附作用
Adsorption of Organobentonite on Omethoate from Water
摘要
Abstract
DTAB-bentonite was synthesized by inserting dodecyltrimenthylammonium bromide ( DTAB) into the in-terlayer of Na-modified bentonite .The adsorption of natural and DTAB modified bentonite on organophosphorus pesti -cide omethoate was investigated using a batch equilibrium technique .The effects of pH , temperature , contact time and dosage of modified bentonite were also observed .The results showed that the DTAB modified bentonite has a better ad-sorption capacity than the unmodified sample , the removal rate to omethoate reached 80.6%at the initial concentration of omethoate was 0.8 g/L under the conditions of pH value 7.0, contact temperature of 25℃, contact time of 30 min, and dosage of modified bentonite of 10 g/L.关键词
