本文陈述以王水处理煤(煤灰)样,制成含砷试液,经K[BH_4]还原后、原子化,在砷无极放电灯辐射下,根据所产生的原子荧光强度来定量测定煤中的砷。
This paper states that coal (coal ash) samples are treated with aqua regia, and the arsenic test solution is made into an arsenic test solution which is reduced by K [BH_4] and atomized. Under the irradiation of arsenic electrodeless discharge lamp, the coal is quantitatively determined according to the atomic fluorescence intensity In the arsenic.
