【摘要】 用相平衡法研究了ZnCl₂/ZnAc₂/ZnSO₄-L-Met-H₂O在25℃及全浓度范围内的溶度性质,结果表明在ZnCl₂体系中存在两种化合物:Zn（Met）Cl₂和Zn （Met）₂Cl₂·2H₂O,而ZnAc₂和ZnSO₄体系均属简单体系,无化合物存在。在相平衡结果指导下,制得上述两种固态配合物,用化学分析确定其组成。IR光谱表明锌离子与蛋氨酸的氧原子和氮原子配位。更多还原

【Abstract】 The solubility properties of ZnCl₂/ZnAC₂/ZnSO₂-Met-H₂O Systems at 25℃in the whole cocentration range have been systematicall investigated by phase equilib- rium methobd.The results indicated that there are two kinds of complex formed in system of ZnCl₂-Met-H₂O:Zn（Met）Cl₂ and Zn（Met）₂Cl₂·2H₂O,and that there were no complex forms fromed in the rest systems at the experiment condition.Under the direction of phase equilibrium result,2 solid complexes,Zn（Met）Cl₂ and Zn （Met）₂Cl₂·2H₂O were synthesized.The results of IR spectra indicated in these complexes of zinc,the ligand L- methionine connects the Zn²⁺inos through the oxygen atom and nitrogen atom.更多还原
