Analysis of Extraction Mechanism and Extraction Equilibrium Constant of La in P204-HCl-HAc System AITranslate
Abstract AITranslate
At pH1,La concentration is determined by EDTA volumetric titration in the two phases of P204-HCl-HAc extraction system,and study is made on the effect of solution acidity and extractant concentration on La distribution ratio.Based on the infrared spectrum testing and analysis of La loaded organic phase in the P204-HCl-HAc system,investigation is made on the extraction mechanism of La in P204-HCl-HAc system and the extraction equilibrium constant is determined.The results show that at pH1,the extraction is actually a displacement reaction between La and group P-OH based on the cation exchange mechanism and complexing and coordination action between La and group P=O with extraction equilibrium constant KLa is 10-0.02.
