采用批量平衡法,研究了6种低分子量有机酸(柠檬酸、酒石酸、苹果酸、乙酸、草酸和丁二酸)对3种粘土矿物(高岭土、蒙脱石、凹凸棒石)吸附二氯喹啉酸的影响。结果表明:当低分子量有机酸存在时,供试3种粘土矿物对二氯喹啉酸的吸附过程可用Linear和Freundlich吸附等温方程描述,且Freundlich方程的拟合效果更好。供试6种有机酸对二氯喹啉酸在高岭土中吸附量的影响程度从低到高依次为苹果酸

The effect of low-molecular-weight organic acids （ citric acid, tartaric acid, malic acid, acetic acid, oxalic acid and succinic acid） on adsorption of quinclorac by three clay minerals （kaolinite, montmorillonite and attapulgite ） was investigated by a batch experimental technique. The results showed that the adsorption isotherm of quinclorac in clay minerals could be well described by Freundlich and Linear equation under the presence of low-molecular-weight organic acids, but the Freundlich equation was more suitable. The tested six kinds...
