氢化物——原子荧光光谱法测定内墙涂料中汞

Test of Hg Content in Interior Wall Coatings with Hydride-Atomic Fluorescence Spectrum

应用XGY - 10 12型原子荧光光度计测定内墙涂料中的汞含量 ,指出硼氢化钾、酸度、炉温等对测定结果的影响 ,在最佳条件下 ,检出限为 0 91μg/kg ,加标回收率为 94 %～97%。

Hg content in interior wall coatings can be tested with XGY-1012 hydride-atomic fluorescence spectrum. This article discusses the influence of kalium borohydride, concentration of acidity, temperature of furnace and etc on tested results, including that the tested limit is 0 91μg/kg under the optimized condition, and recovery rate with standards is 94%～97%.
