本文在温度２５±０．１℃、离子强度为０．１ｍｏｌ／Ｌ（ＮａＮＯ３）的４０％二氧六环－水（ｖ／ｖ）介质体系中，测定了六种氨基酸的酸解离常数及其铜配合物的稳定常数．比较了纯水与混合溶剂情况下，氨基酸配体的解离变化和金属铜配合物的稳定性，讨论了有机溶剂组份在氨基酸配体酸解离过程及金属铜离子配位过程中的影响作用．对于二元金属配合物中可能存在的配体间相互作用进行了讨论
In this paper, the acid dissociation constants of six amino acids were determined in a 40% dioxane-water (v / v) system with a temperature of 25 ± 0.1 ℃ and an ionic strength of 0.1 mol / L (NaNO3) Its copper complex stability constants. The effect of organic solvent on the dissociation of amino acid ligands and the stability of metal copper complexes was compared with that of pure water and mixed solvents. The effects of organic solvent components on the dissociation of amino acid ligands and coordination of copper ions were discussed effect. The possible inter-ligand interactions in binary metal complexes are discussed
