| Abstract: | 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 SO2-4 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. |
