摘　　要：目的:研究蒙脱石对醋酸氯己定的吸附特性。方法:采用紫外分光光度法测定不同浓度的醋酸氯己定溶液加入一定量蒙脱石后的含量。结果:蒙脱石对醋酸氯己定有强烈的吸附,可用Langmuir吸附等温式表征其吸附特性。饱和吸附量达371.6mg·g-1。结论:吸附氯己定可使蒙脱石具有杀菌功能。Objective: To study the adsorption properties of montmorillonite in chlorhexidine acetate solution. Method: The contents of chlorhexidine acetate after morillonite added into the different concentration of chlorhexidine acetate solutions were determined by UV. Result: Montmorillonite adsorpted chlorhexidine acetate, the adsorption properties by Langmuir equation of adsorb on the adsorption was analyzed, Гm =371.6 mg·g-1. Conclusion: Montmorillonite had a bactericidal effect after adsorping chlorhexidine acetate.
