摘要
本文将水溶液雾化进样与微波等离子体炬原子荧光光谱法联用,建立了HCL-MPT-AFS测定Zn的新方法。讨论了实验条件的选择问题以及溶液中共存离子对测定Zn的影响,本文所推荐的方法具有较高的灵敏度和精密度,并将其用于实际样品分析。
A novel method of microwave plasma torch-atomic fluorescence spectrometry (MPT-AFS) has been proposed. A new improved microwave plasma torch was used as an atomizer, and a pneumatic nebulizer was used for introducing aqueous sample. The analytical performance of MPT-AFS for zinc was investigated. The detection limits for zinc and cadmium Were 1. 2 and 0. 26 ng/ml,respectively. The method proposed has also been used to analyze the practical samples for zinc with satisfactory results.
