摘要
提出了用可逆模型进行曲线拟合处理数据,并以稀土偶氮肿Ⅲ络合物与CyDTA交换反应为例作验证,结果理论曲线与实验曲线能很好地吻合,提高了用动力学法测定混合稀土的准确度。
In this paper, an imitation of the experimental data with a mathematical model for the reversible reaction has been proposed, which is corroborated by the ligand-exchange reacion between RE-ArⅢ (the coordination compound of rare earth and arsenazo Ⅲ) and CyDTA. By the method, the experimental curve is in good agreement with the theoretical, so the accuracy for the determination of rare earth mixture by differential kinetic analysis is improved.
