摘要
常温下,以壳聚糖和酸性粉煤灰为原料,制备壳聚糖交联酸性粉煤灰吸附剂;用光度法分析其对M n2+的吸附性能。结果表明:交联时,当壳聚糖与酸性粉煤灰的质量比为1∶11,交联剂用量为2mL/g;吸附时,废水pH为6,吸附时间为90min,吸附剂用量为10g/L时,M n2+去除率为97.6%。
The composite adsorbent was prepared with chitosan and acid modified fly ash at room temperature. The absorption performance of it on Mn2+ was analyzed by spectrophotometry. The result show that: under the mass ratio of the chitosan and acid modified fly ash 1:11,the dosage of crosslinking agent 2mL/g and with the adsorption conditions the waste water pH was 6,adsorption time was 90min,the mass of adsorbent was 10g/L,the removal rate reach to 97.6%.
