摘要
采用十六烷基三甲基溴化铵和壳聚糖对钠基膨润土改性,制得纳米改性膨润土复合材料(以下简称纳米改性土),研究其对苯酚的吸附行为。结果表明:改性剂成功负载于钠基膨润土片层表面;改性剂掺杂量、活化反应时间、pH值和吸附时间均会影响其吸附性能;吸附机理主要表现为分配作用和吸附电中和作用。
Modified bentonite nanocomposite materials were produced by sodium bentonite,hexadecyl trimethyl ammonium bromide and chitosan.Adsorption activity to phenol was researched.The results indicated that modifier was successfully loaded on the surface of sodium bentonite.Adsorption property was effected by modifier mass,reaction time,pH and adsorption time.Adsorption mechanisms were mainly distribution function and electricity neutralization.
