【摘要】 用离子交换法和原子吸收分光光度法研究了黄河水中固体粒子与重金属Zn2 +、Cd2 +相互作用的等温线 ,得到一个“拐点”两个“平台”的新型河流等温线。在黄河水中 ,固体粒子与两种金属离子进行阳离子交换反应 ,交换过程是分二级进行的更多还原

【Abstract】 The isotherms of the interaction between solid particles and heavy metals Zn 2+ , Cd 2+ in the Yellow River water were studied by ion exchange method and atomic absorption spectrophotomery. The isotherms are a new river isotherms in which te whole curve is formed from two curves combined together with a “plateu” in the middle. Between the solid particles and heavy metals the cation exchange takes place in the Yellow River. The exchange processes are stepwise.更多还原
