The Mathematical Model for Simultaneous Determination of Rare Earth Mixture with Differential Kinetic Analysis by Means of Ligand-Exchange Reaction

Abstract

Abstract: 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.

Key words: Rare earth, Differential kinetic analysis, Ligand-exchange reaction, Reversible model
