摘　　要：建立密封消解氢化物发生原子荧光光谱同时测定PVC中铅和汞的方法。对密封消解原子荧光光谱法同时测定铅和汞的各参数条件进行研究。在最佳测试条件下，铅方法捡出限为0．04ng／ml，样品加标回收率为97．4％～103．0％；汞方法检出限为0．02ng／ml，样品回收率为96．0％-99．6％。本法具有快速、准确、灵敏度高、精密度好等优点，用于PVC及其制品中总铅和总汞的测定，结果满意。A method was established by sealing digestion AFS - 230E for simultaneous determination of lead and mercury in PVC . Parameters of atomic fluorescence spectrometry for the method were studied. Under the optimum testing conditions, the detection limit of lead was 0.04ng/ml and sample recovery rate was 97.4% -103.0% ; and the detection limit of mercury was 0.02ng/ml and sample recovery rate was 96.0% - 99.6%. The method is rapid,convenient, accurate, sensitive and suitable for determination of lead and mercury in PVC.
