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.
