L-苏糖酸与Mn(Ⅱ)、Hg(Ⅱ)的配位性能研究

Studies on the Coordination Reaction of L threonate Acid with Mn(Ⅱ) and Hg(Ⅱ)

本文在前文的基础上，研究了Ｌ－苏糖酸与Ｍｎ（Ⅱ）、Ｈｇ（Ⅱ）的配位性质，测定了所形成的二元配合物的稳定常数，Ｍｎ（Ⅱ），５．２２（１２０）；Ｈｇ（Ⅱ），３．６０（１１０），６．１１（１２０），对其配位性质与同族元素进行了比较研究．

The complex formation constant of L threonate acid with Mn(Ⅱ) and Hg(Ⅱ) binary complex were dertermined at 298K, I =0.1mol·L -1 KNO 3. The resauts are: Manganese (Ⅱ),5.22(120);Mercury (Ⅱ),3.60 (110),6.11(120).Compared with Zn(Ⅱ) and Cd(Ⅱ),the formation constant of Hg(Ⅱ) is the largest.
