| Abstract: A functional-link net(FLN) was applied to study the relationships between the structural parameters of metal ions and their Hytrosis Constants pK1. These structural parameters such as radius, electric charge, electronegativity (electricity shouldering) and valence electron structure parameter of the metal ion. The results are satisfactory, and better than that obtained by using linearly statistic methods. Through comparing hytrolysis constants pK1 with hydration-energy ΔH, the non-linear characteristic of pK1 have deeply discussed. 19 unknown pK1 of metal ion were predicted with the method. |
