摘要
试样于潘菲氏管中加入还原铁粉 ,加热使汞与基体及共存元素分离 ;试验了氢化物 -原子荧光光谱法测定汞的最佳条件。汞的检出限为 0 0 5ng/mL ,线性范围为 0 5～ 2 5 0ng/mL ,汞的回收率为 94%～ 10 1%。方法应用于锌精矿中汞的测定 。
Add the reduced iron powder into Panfei tube contained the sample,heat to make mercury separated from coexisting elements;The optimal conditions for the determination of mercury by hydride generation atomic fluorescence spectrometry were studied The detection limit of mercury is 0 05ng/mL the linear range is 0 5-250ng/mL for Hg*',the recoveries of mercury are 94%-101% The method has been applied to determine mercury in zinc refined ores with satisfactory results
