| 英文摘要 | Relative metal-ligand complex stability is predicted by evaluating the relationships between physicochemical properties of metal ions and their experimental biotic and abiotic binding constants, K. Linear regression analysis showed that the softness index (sigma(p)) and the covalent index (chi(2)(m)r) were especially useful in model construction for rainbow trout (Oncorhynchus mykiss), fathead minnows (Pimephales promelas) and crustaceansaquatic (Daphnia magna) based on RMSE and F-ratio criterion (F(observed)/F(critical) of >= 4). The absolute value of the log of the first hydrolysis constant |log K(OH)| correlated best with log K values for barley (R(2)=0.74, p=0.02) and earthworm (R(2)=0.82, p=0.01). In contrast, the ionic index Z(2)/r explained most of the variability of log K values for the two clays kaolinite and montmorillonite, while |log K(OH)| was a better predictor of the generic NICA-Donnan parameters for HA and FA (0.67 < R(2) < 0.80, 0.002 < p < 0.01). This implies dissimilarity of the nature of the binding sites on biotic and chemical ligands and the different binding mechanisms between metal and ligands. (C) 2011 Elsevier Inc.
