为明确咪鲜胺在蒙脱石、高岭石、凹凸棒石和海泡石4种粘土矿物上的吸附行为及作用机理,采用批量平衡实验法,利用HPLC和FT-IR进行了测定和分析。结果表明,4种粘土矿物对咪鲜胺的吸附12 h内均可达平衡,Elovich方程为最佳模型(R~2>0.88, P0.93, P

To elucidate adsorption characteristics and mechanisms of prochloraz on montmorillonite, kaolinite, attapulgite and sepiolite, batch equilibrium methods were used to detect and measure the adsorption amount of prochloraz using HPLC and FT-IR. The results indicated that adsorption of prochloraz on four clay minerals both reached equilibrium within 12 h, and Elovich equation was the best adsorption kinetic model（R2〉0.88, P〈0.05, n=9）. The isothermal adsorption of prochloraz on montmorillonite, kaolinite and sepiolite could be fitted by Langmu...
