摘要:首次研究了新型羧酸类萃取剂CA-100对铟(Ⅲ)的萃取性能,考察了各种条件对萃取的影响.通过斜率法、等摩尔系列法及饱和容量法确定了萃合物的组成为InA3,萃取反应实质为阳离子交换反应.
The extraction behavior and mechanism of indium with CA--100 have been studied. Effects of parameters such as the initial pH, concentration of CA--100, concentration of indium( Ⅲ ) ion and concentration of SO^2-4 on extraction percentage were investigated. It is found that indium( Ⅲ )was quantitatively extracted with CA--100 at pH range of 2.50-3.20. The stoichiometry of the extracted species of indium( Ⅲ ) was determined using the slope-analysis method, constant molecular series method and saturation capacity method. The extracted species are in the form of InA3. The extraction reaction proceed via a cation exchange mechanism.
