摘要
本文对稀土硝酸盐与甘氨酸生成的配合物 RE(NO_3)_3·(Gly)_4Ln=La.Ce.Pr.Nd.Sm.Eu.Gd.Tb;Gly=Gly(cine)进行了 TG—DTG.DSC 分析,确定了配合物的热分解过程,比较了配合物的热稳定性;利用 Kissinger 公式计算了配合物的表现分解活化能;从 DSC 分析得到了配合物的相变焓。
In this paper,the solid complexes whose compoments are Ln(NO_3)_3·(Gly),(Ln =La.Ce.Pr.Nd.Sm.Eu.Gd.Tb;Glycine)are determined by usiny element analysis,Chemical analysis and thermogravimetry.The thermal decomposition stages and the intermediates of the Complexes are examined by means of TG·DTG and DSC.Meanwhile,their thermal stability are Compared.The apparent decomposition activition energy of the complexes are computed by kissinger formual,and their phase change enthalpy are studied by DSC
