摘要
研究在盐酸羟胺底液中 ,用单扫示波极谱法测定CNI合金中的铟。结果表明 ,无需分离基体 ,单扫示波极谱法可用于CNI合金中铟的直接测定。测定的线性范围为 0 0 0～ 5 0 0 0 μg/mL ,检出限为 0 0 0 2 μg/mL ,对含铟 4 68%的CNI合金 ,测定RSD小于 3 2 % ,加标回收率为 96%～ 10 2 %。方法准确、灵敏、线性范围宽 。
The analysis of Indium in CNI alloy by using single sweep polarography in 150g/L NH 2OH·HCl solution is investigated The results show that In in CNI alloy without separation can be directly determined by single sweep polarography method The well determining range is 0 0～50mg/L, and the limit of detection for In is 0 002mg/L, and recovery is 96%～102% This method is precise, sensitive, wide linear range and easy operation
