报道了 N ,N -二辛基甘氨酸从盐酸体系中萃取钯的机理 ,结果表明 :钯的萃取率随酸度、氯离子浓度、钯离子浓度的增大而降低。采用斜率法测得萃合物组成为 :R2 NCH2 COOH· HHPd Cl4,其萃取反应式为 :R2 NCH2 COOH· HCl( O) +HPd Cl- 4 ( A) =R2 NCH2 COOH· HHPd Cl4( O) +Cl- ( A)
The mechanism of extracting palladium from hydrochloric acid with N, N - dioctylglycine was reported. The results showed that the extraction rate of palladium decreased with the increase of acidity, chloride ion concentration and palladium ion concentration. Using the slope method, the extraction composition is as follows: R2 NCH2 COOH · HHPd Cl4, the extraction reaction is: R2 NCH2 COOH · HCl (O) + HPd Cl- 4 (A) = R2 NCH2 COOH · HHPd Cl4 (O) + Cl- (A)
