摘　　要：在对Cr^3+和亚甲基蓝模拟的工业废水分别进行单因素研究的基础上,经过考察溶液的pH值、浓度、温度、分子筛添加量等因素之后,采用振荡吸附法对低浓度Cr^3+和亚甲基蓝混合废水进行吸附研究。结果表明,利用粉煤灰制备的ZSM-5分子筛对单一Cr^3+和亚甲基蓝废水的吸附率分别为73.10%和98.20%;对混合废水同时有着良好的吸附效果,分子筛对混合废水中Cr^3+和亚甲基蓝吸附率达77.14%和93.61%。The single-factor adsorption of mixed waste water with Cr^3+and methylene blue was studied by means of oscillating adsorption and the factors such as pH value,concentration,temperature and molecular sieve addition were investigated.The results showed that ZSM-5 molecular sieves prepared from fly ash had better adsorption effect on the mixed waste water.The adsorption removal rate of single Cr^3+and methylene blue were 73.10%and 98.20%.The adsorption removal rate of Cr^3+and methylene blue in the mixed waste water reached 77.14%and 93.61%.
