摘要
采用增压溶样器加７：３：５的ＨＮＯ３－Ｈ２ＳＯ４－ＨＣｌＯ４混合酸处理煤样．用冷原子荧光法测定煤样中的总汞含量。该法的加标回收率为９２．７～１１２．５％，结果令人满意。
A method was developed for determination of mercuryin coal with cold vapor atomic fluorescence spectromtry after pressure acid digestion of acid mixtures of HNO3-H2SO4-HClO4(7:3:5).Its recovery was in the range 92;6-112.5%.The results were satisfactory.
