摘要
用分光光度法研究了氯化钠和四丁基溴化铵浮选分离金的行为及与一些金属离子分离的条件。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,pH3.0时,Au(Ⅲ)可与U(Ⅵ)、Ce(Ⅲ)、Mg(Ⅱ)和Cu(Ⅱ)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 were investigated with NaCl-tetrabutyl ammonium bromide system by spectrophotometry.The results showed that Au(Ⅲ) could be quantitatively separated from U(Ⅵ),Ce(Ⅲ),Mg(Ⅱ) and Cu(Ⅱ) when the concentrations of NaCl and tetrabutyl ammonium bromide in solution(pH 3.0) 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 the sample of synthetic water with satisfactory results.
