摘　　要：为了提高蒙脱土对双酚A的吸附性,笔者用十八烷基三甲基溴化铵(STAB)和硝酸银溶液制备了银掺杂改性有机蒙脱土,研究了pH值、吸附时间、固液比、吸附温度对双酚A去除率的影响。试验结果表明,吸附时长为60min,固液比为1∶30,pH为5.0,体系温度为30℃时,吸附效果最佳。In order to improve the adsorption of bisphenol A on montmorillonite, organic montmorillonite modified silver doped was prepared with octadecyl trimethyl ammonium bromide （STAB） and silver nitrate solution. The influence factors of pH, adsorption time, solid-liquid ratio and adsorption temperature on the removal rate of bisphenol A were studied. The results showed that when the adsorption time was 60min, solid-liquid ratio was 1：30, bisphenol A, pH=5, the system temperature was 30℃ , the adsorption effect was best.
