摘要：

本文用旋光法研究了钼(Ⅵ)-L-天冬酰胺配合物的最大配位数, 用pH电位法研究了钼(Ⅵ)-L-天冬酰胺及钼(Ⅵ)-L-天冬氨酸配合物, 证实它们都生成1:1型配合物。测定了配合反应的热力学参数ΔHø、ΔGø、ΔSø并对它们进行了讨论。

Abstract:

The maximum coordination number of complex of molybdenum (Ⅵ) with L- Asparagine has been determined by polarimetry. The complexes with 1:1 form in the systems of Molybdenum (Ⅵ)-L-Asparagine and Molybdenum(Ⅵ)-L- Aspartic acid were demonstrated by pH potentiometric studies. The thermodynmic parameters ΔHø、ΔGø、ΔS~ø of these coordination reactions have been reported and discussed in this paper.
