摘要
研究了氯化钠和四丁基溴化铵分离金的行为及与一些金属离子分离的条件。实验结果表明,当溶液中氯化钠和四丁基溴化铵的浓度分别为2.5×10-3mol/L和4.0×10-4mol/L时,Au(Ⅲ)可与Ga(Ⅲ)、Co(Ⅱ)、Pd(Ⅱ)、Zn(Ⅱ)、Rh(Ⅲ)、Al(Ⅲ)、Cd(Ⅱ)、Ce(Ⅳ)、Fe(Ⅲ)、Ru(Ⅲ)、Cu(Ⅱ)、W(Ⅵ)、Ti(Ⅳ)、Pb(Ⅱ)、Sb(Ⅲ)、V(Ⅴ)、Pt(Ⅳ)、Mn(Ⅱ)I、n(Ⅲ)、Sn(Ⅳ)、Ni(Ⅱ)I、r(Ⅳ)和Cr(Ⅲ)离子定量分离,对合成水样中Au(Ⅲ)的分离和测定,结果满意。
The behavior and conditions for the flotation separation of Au(Ⅲ) from other metal ions in NaCl-tetrabutyl ammonium bromide system were investigated. The results showed that Au(Ⅲ) could be quantitatively separated from Ga(Ⅲ), Co(Ⅱ), Pd(Ⅱ), Zn(Ⅱ), Rh(Ⅲ), Al(Ⅲ), Cd(Ⅱ), Ce(Ⅳ), Fe(Ⅲ), Ru(Ⅲ) ,Cu(Ⅱ) ,W(Ⅵ), Ti(Ⅳ) ,Pb(Ⅱ) ,Sb(Ⅲ) ,V(Ⅴ) ,Pt(Ⅳ) ,Mn(Ⅱ) ,In(Ⅲ) ,Sn(Ⅳ) ,Ni(Ⅱ), Ir(Ⅳ) and Cr(Ⅲ) by flotation when the concentrations of NaC1 and tetrabutyl ammonium bromide in solution were 2.5×10^-3mol/L and 4.0×10^-4mol/L, respectively. The method has been used for the separation and determination of Au(Ⅲ) in water samples with satisfactory results.
