生物吸附剂 Bio －matrix 去除废水中重金属的研究
Heavy Metal Removal by Bio-matrix Biosorbent
摘要
Abstract
Objective] To research the adsorption performance of biosorbent Bio-matrix on conventional heavy metal Cu , Ni 2 + and Cr . [Method] Effects of pH, temperature, biosorbent dosage and adsorption time on adsorbing capacity were researched, isothermal adsorption of Bio-matrix to Cu 2 + was analyzed.[Result] Bio-matrix had better adsorption effects to Cu 2 + than Ni 2 + and Cr 3 +.Unit adsorption capacity firstly enhanced and then decreased with pH, and reached the maximum at pH 4.The adsorption isotherm of Cu 2 + had better fitting with the Freundlich equation, and the saturated adsorption capacity was 19.3 mg /g.[Conclusion] This research provides feasible way for the heavy metal removal by Bio-matrix biosorbent.关键词
