摘要
在6mol/LHCl介质中,有TiCl3存在条件下,用甲苯-甲基异丁基酮萃取分离镓,用罗丹明B作显色剂,以分光光度法测定镓,镓的质量浓度在0～0.5mg/L范围内符合比耳定律。该方法灵敏度高,大多数常见阳离子不干扰测定,用于铝酸钠溶液中微量镓的测定,结果令人满意。
Determination method of gallium in sodium aluminate solution has been developed.In 6mol/L HCl medium,gallium can be extracted with methylbenzeneMIBK at the present of TiCl3,then is determined using Rhodamine B as coloring agent by spectrophotometry.The Beer Law is obeyed in the range of 0~0.5 mg/L for mass concentration of gallium.The results show that the method has higher senstive, and many coexisted cations doesn't interfere the determination of gallium.The method has been used in determination of gallium in sodium aluminate solution with satisfactory results.
