摘　　要：用酸和溴化十六烷基三甲基铵(HDTMA)对沸石改性并进行了表征,探讨了吸附剂的浓度、投入量、反应温度、时间、pH值各因素对Cr(VI)去除率的影响。结果表明,通过HDTMA改性后的沸石,吸附除铬的效果显著。当HDTMA浓度为1.0%、温度为20℃、反应时间为10min、吸附剂投入量为16g/L、pH=5时,Cr(VI)的去除率可达94.0%。The zeolite was modified and characterized by using Hydrochloric acid and acetyl trimethyl ammonium bromide（HDTMA）,then the influence of adsorption effect such as concentration of HDTMA,temperature,time,dosage of adsorbent and pH of chromium was studied.It showed that concentration of HDTMA was 1.0,the temperature was 20,the time was 10 min,dosage of the adsorbent was 16 g/L,the pH value of chromium was 5.removal efficiency of Cr（VI）was 94.0%.
