| Abstract: | In this paper,the conditional stability constants of complexes of heavy metal(Cd andPb)and humic acids from Xiang Jiang river sediment,Linshi weathered coal and Dedu peatshave been estimated.At the same time,complexing capacity and molecular weight have been estimated too. We have also investigated the effects,sources of errors and the methods for eliminating them. |
