摘　　要：文章制备了银掺杂十八烷基三甲基溴化铵改性蒙脱土(Ag/STAB-MMT),研究了Ag/STAB-MMT对苯酚的吸附性能。结果表明,Ag/STAB-MMT对苯酚的吸附性能优于蒙脱土、STAB改性蒙脱土及银掺杂蒙脱土;在温度为20℃、p H=10.0、吸附时间为120min的条件下,吸附剂用量为2.5g/L时银掺杂改性蒙脱土对对苯酚的吸附率最大。In this paper, we have studied phenol-absorptivity of silver-doped octadecyl trimethyl ammonium bromide （STAB） modified montmorillonite （Ag/STAB-MMT） which was prepared in laboratory based on the standard method. The result shows that the phenol-absorptivity of Ag/STAB-MMT was higher than montmorilloni STAB modified montmorillonite and silver-doped montmorillonite. It was found that the phenol-absorptivity te, of Ag/STAB-MMT had the highest value at the conditions for which the concentration of substance was 2.5g/L, time duration for absorption was 120 min, and temperature was 20℃ with pH of 10.
