摘要
提出了从电位溶出滴定曲线求金属的络合容量及络合物条件稳定常数的一般理论方法,并将此法用于西安兴庆湖水中有机配体与铅的络合容量和络合物的总平均稳定常数的测定,获得满意结果。
A theoretical method to estimate the complexation capacities and the complex con-
ditional stability constants of heavy metals with the ligand in aquatic environment ac-
cording to potentiometric stripping titration curves has been developed. This method is
applied to determine the two complexation parameters of lead ion with organic ligand in
the water of Xinqing Lake in Xi'an, and the results are quite satisfactory.
