摘要
采用电感耦合等离子体原子发射光谱-标准加入法（ICP-AES-标准加入法）探讨铝合金中痕量钠的测定.以盐酸、过氧化氢溶解试料,优化全谱型ICP-AES分析条件,标准加入法测定铝合金中痕量钠,检出限为0.028 μg/mL（588.995 nm）.用该方法测定铝合金中0.00014％～0.00073％钠含量,加标回收率在92％～110％之间,连续测定5个结果的相对标准偏差小于0.25％.
A method was studied for the determination of trace sodium content in aluminum alloy by ICP - AES. By using hydrochloric acid and hydrogen peroxide 30% to dissolve samples, trace sodium content in the aluminum alloy were determined according to the optimum condition of ICP - AES. the detection limit were 0. 028 μg/mL（588. 995nm）. The results of trace sodium content were between 0. 00014% - 0. 00073%. The relative standard deviations of five samples was less than 0. 25%.
