摘要
采用十六烷基三甲基溴化铵(CTAB)和壳聚糖对沸石进行改性,并考察了改性沸石对垃圾渗滤液的脱色性能。结果表明:通过改性,沸石的脱色能力明显得到改善,CTAB改性效果优于壳聚糖。用浓度为10%的壳聚糖和CTAB溶液修饰沸石,在垃圾渗滤液的初始pH调为7~8,改性沸石用量为4.0g/100mL的条件下,其对垃圾渗滤液的脱色率分别达到74.3%和81.5%。
Zeolite was modified using CTAB or Chitosan as modifier, and its decolorization performance toward trash leachate was stud- ied. The results show that, after modification, decolorization capacity of the zeolite is significantly improved. The modified effect with CTAB as modifier is better than with Chitosan as modifier. The deeolorization rate of trash leachate was up to 74.3% and 90.0% respectively using the Chitosan concentration of 10% and CTAB to modify the zeolite, under the condition of the pH from 7 to 8 and the zeolite dosage of 4.0 g/100mL.
