污水排放对泥砂吸附Cu^(2+)的影响

Effects of Waste Water on the Adsorption of Sediment for Cu 2+

本文研究了污水排放对泥沙吸附Ｃｕ２＋的影响．结果表明影响吸附的主要因素是有机物的浓度和体系的ｐＨ值．低浓度的有机物对吸附起促进作用，高浓度的有机物对吸附起抑制作用；低ｐＨ对吸附影响不大，高ｐＨ对吸附的影响较大，特别是ｐＨ６～７影响最为显著．给出了体系的离子交换的ｐＨ范围公式．探讨了“Ｓ型曲线”

This paper deals with the effects of waste water on the adsorption of sediment for Cu 2+ .The experiments show that the concentration of organic materials and pH affect the adsorption.The organic materials of low concentration promotos the adsorption but the high concentration restrains it.The influence on the adsorption of low pH is little and the high pH is significant especially in the value of 6～7.It gives the equation of pH range in the ionic exchange of the system and disscusses the swinging law and mechanics of 'S-cruve'.
