摘要
使用无机离子交换法研究珠江口水体中铜与悬浮颗粒物的相互作用，测出钢与悬浮颗粒物相互作用的ｐＨ曲线呈Ｓ形，其分级离子交换等温线是一种新的“台阶”型；从分级离子交换理论求得分级平衡常数Ｋ１为５．０，Ｋ２为７８．１，珠江口水体中铜的表观络合容量为０．９２μｍ及其条件稳定常数为３．５×１０７。
The interaction between Cu (Ⅱ) and suspended matter in Zhujiang River Estuary was studied using the inorganic exchange method. The results show that the interaction between Cu (Ⅱ) and supended matter has a S-shaped pH curve, and its stepwise ion-ex-change isotherm presents a new 'step' type. From the theory of stepwise ion-exchange,the stepwise equilibrium constants (K1) and (K2) of Cu (Ⅱ) on suspended matter are calculated to be 5.0 and 78.1, respectively, while the apparent complexing capacity and conditional stability constant of Cu (Ⅱ) are 0.92 μm and 3.5×107, respectively.
