摘　　要：通过考察温度、振荡时间和醋酸浓度对活性炭吸附醋酸的影响,确定了不同温度下的最佳醋酸浓度范围和振荡时间等实验条件,并分析了该法产生测试误差的原因,从而降低了温度、溶液浓度及振荡时间等因素的影响。该实验既有物理化学实验中的固液吸附理论知识和实验操作,也涉及到了仪器分析实验中的氮吸附比表面积测定仪的使用,所以本实验可以作为化学专业硕士研究生的综合化学实验。The influences of temperature,time of oscillation and concentration of acetic acid on the adsorption of acetic acid on activated carbon were investigated.The optimum conditions of acetic acid concentration and oscillation time at different temperatures were determined,the reasons for the test error were analyzed,and the effects of temperature,solution concentration and oscillation time were reduced.The experiment included theoretical knowledge and experimental operation of solid-liquid adsorption in physical and chemical experiments,it also involved the application of nitrogen adsorption surface area tester in instrumental analysis experiment.Therefore,this experiment can serve as a comprehensive chemical experiment for master of chemistry.
