| Abstract: | Using butyl acetate to extract Ga in 6.0mol/L HCI medium, Ga will be determinated by using flame atomic absorption after water reextracting. The method has a linear range for Ga as 0～100μg/mL with the detection limit being 0. 028μg/mL. The recoveries of standard addition are in the range of 97. 9～101.8% with RSDs between 2.83% and 3. 96%. Satisfactory results have been achieved by applying this method to determinating Ga in Bayer solution. |
