Research on the Treatment of Cr(Ⅵ)-containing Wastewater by Fly Ash-chitosan Adsorbent

ZHENG Binguo,LI Jianyun,CUI Jiehu,NIU Junling(Institute of Resources and Environment,Zhengzhou Institute of Aeronautical Management,Zhengzhou 450015)  
A kind of adsorbent is made by coating chitosan on the surface of fly ash,its adsorptivity toward Cr(Ⅵ)from aqueous solution is studied,and the optimal condition for Cr(Ⅵ)adsorption is discussed in details.The results show that,the adsorbent has good adsorptivity toward Cr(Ⅵ),the optimal condition for the adsorption process is as follows:the temperature is 25℃,the value of pH is 5,initial mass concentration of Cr(Ⅵ)is 20mg/L,the dosage of adsorbent is 10g/L,the adsorption equilibrium time is 1h,and the removal ratio of Cr(Ⅵ)is over 90%.
