摘　　要：实验以天然钙基膨润土为原料,经过改性制备出了锂基膨润土。探索了膨润土用量、松香酸浓度、吸附温度、吸附时间对松香酸吸附的影响,最后对锂基膨润土吸附松香酸的机理进行了研究。结果表明:吸附松香酸最佳条件为:反应时间90 min,反应温度50℃,松香酸浓度500 mg·L-1,膨润土用量200 mg·L-1;经过改性后,膨润土的吸水性和吸附量都有了一定的提高。Natural bentonite was choosen as raw materials and orgamc oentonlte was plcVal^u oy different dosage of bentonite, different concentration of abietic acid, different adsorption temperature and different adsorption time on the adsorption of abietic acid were studied. The results show that the best conditions for adsorption is when the time is 90 rain, the temperature is 60℃, the concentration of abietic acid is 500mg·L ^-1, the dosage of bentonite is 200mg·L^-1. The absorbent and adsorption of bentonite have been improved to some extent.
