水杨醛牛磺酸Schiff碱镝(Ⅲ)配合物的合成表征及热分解动力学研究

摘要

合成了水杨醛牛磺酸Schiff 碱与镝(Ⅲ)的配合物,并通过元素分析、红外光谱、X射线粉末衍射及摩尔电导等对其结构进行了表征.在非等温条件下,采用Achar微分法和 Coats-Redfern积分法拟合出配合物的热分解动力学方程.%A complex of dysprosium (Ⅲ) with Schiff base of salicylaldehyde-taurine and 1,10-phenanthroline was synthesized. The composition of the title complex was characterized by elemental analysis,EDTA volumetic analysis,IR,molar conductivity and X-ray powder diffraction. The thermodecomposition kinetics of the complex was investigated under the condition of non-isothermal using the Achar differential method and the Coats-Redfern integral method.
