镧系元素异硫氰酸盐与甘氨酸配合物的热解过程及热解动力学研究

The Study on the Process and Kinetics of Thermal Decompsition of the Complexes of Lanthanide Isothiocyanates with Glycine

本文叙述了三种镧系元素异硫氰酸盐与甘氨酸(GLy,NH_2CH_2CooH)的固体配合物Ln(NCS)_3·3GLy·H_2O进行了研究,确定了它们的热分解过程,用Coats—Redfern法求出了它们的第二步热分解过程的动力学参数。

In this paper, the synthesis method of the complexes of Ln(NCS)_3·3GLy·H_2O(Ln+Ce, Pr, Nd) has been described. By TG-DTG thermal analysis, the process of the thermal decomposition has been determined, and by Coats-Redfern's method, the kinetic parameters of the second process has been determined.
