| 摘 要： | 用微波等离子体炬原子发射光谱法(MPT-AES)测定钝镍剂中金属锑的含量。考察了微波功率、载气流量、工作气流量、氧屏蔽气压力、酸效应、共存离子等实验参数对测定的影响,得出了测定钝镍剂中金属锑的最佳工作条件,测得锑的检出限为1.9μg/L,线性范围在0.01～100mg/L,回收率在99.2%～100.3%,精密度(RSD)为2.10%。

| Abstract: | The analytical method for antimony element in nickle passivator was studied by microwave plasma torch atomic emission spectrometry(MPT-AES).Using microwave plasma torch(MPT) as excitation light source,argon as support and carrier gas,and peneumatic nebulization sampling system.Some experimental parameters,including microwave forward power,flow rate of carrier gas and support gas,oxygen shield pressure,effect of acid,coexistence ions were investigated and optimized.The detection limits was 1.9 μg/L.The recover was in the range of 99.2%～100.3%,and its RSD was 2.10%.The Linear range of the antimony elements was 0.01～100 mg/L.MPT-AES was an effective and practical method for determination of antimony in nickle passivator. |
