摘要
对镱甘氨酰甘氨酸配合物的离解动力学进行了研究。结果表明 ,在 p H值为 2 .2 7时 ,配合物的离解呈现一级动力学规律 ,随着温度的升高 ,离解速度增大 ,而当 p H=2 .75、4 .0 0、5 .0 0、6 .0 0时 ,配合物均不发生离解。
In this paper,the complex Yb(Gly-Gly) 2Cl 3·3H 2O has been synthesized and its dissociation kinetics has been studied.As a result,first order kinetics mode for the complex dissociation was shown in the medium of pH=2.27 and the dissociation velocity was increased with the temperature rising,but the complex did not dissociate in the medium of pH=2.75,4.00,5.00,6.00.
