Study on Floatation Sepearation of IrI62- from Common Metal Elements by Spectrophotometric

摘要: 用分光光度法研究碘化钾-四丁基溴化铵体系浮选分离IrI2-的行为及其与常见离子分离的条件.实验结果表明,控制pH1～2.8,能使IrI26-与Sn(Ⅳ),Co(Ⅱ),Mn(Ⅱ),Fe(Ⅱ),Zn(Ⅱ),Al(Ⅲ),Cr(Ⅲ),Ni(Ⅱ)和Mg(Ⅱ)分离

Abstract: The flotation separation behavior of IrI6(2-) with KI-tetrabutyl ammonium bromide system and the conditions for the separation of IrI2-6 with other metal ions were studied by spectrophotometric.It showed that IrI2-6 can be separated completely from Sn(Ⅳ),Co(Ⅱ),Mn(Ⅱ),Fe(Ⅱ),Zn(Ⅱ),Al(Ⅲ),Cr(Ⅲ),Ni(Ⅱ) and Mg(Ⅱ) by floatation at pH1～2.8
