| Abstract: | 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%. |
