氢化物发生—原子荧光光谱法测定饮用水中锡

Determining Tin in Drinking Water with Hydride Generation-Atomicfluorescence Spctrometry

应用氢化物发生—原子荧光光谱法测定饮用水中锡,此法准确度、精密度令人满意。实验选定最佳工作条件:载气400mL/min,屏蔽气800mL/min,灯电流60mA,负高压-320V。方法检出限为0.34μg/L,线性范围为(0～40.0)μg/L。目前测定饮用水中的锡国家还没有制定标准检验方法,本文的工作可为饮用水中锡的标准检验方法的制定做些探索。

Hydride generation-atomic fluorescence spectrometry is used to analyze tin in drinking water. Experiment is done in best work condition;carry gas 400mL/min,closed gas 800mL/min,furnace high 8mm,bulb electric current 60mA, negative high voltage-320V, The determination limit of tin is 0. 34uμg/L,the linear rangeis (0-40. 0)μg/L. The method is simple and sensitive. It is satisfactory in precise and meticulous. There are no standard methods of nation determining tin in drinking water. Our work is to explore the method of determining tin in drinking water.
