火焰原子吸收法测定土壤中铜和铅

Determining Copper And Plumbum In Soil With Flame Atom Absorbane Method

本文建立了逆王水-高氯酸-氢氟酸分解法对土壤进行前处理,氘灯校正背景火焰原子吸收法分析土壤中铜和铅的方法。对逆王水-高氯酸-氢氟酸分解法和王水-高氯酸-氢氟酸分解法两种土壤前处理方法,对氘灯校正背景火焰原子吸收法和萃取火焰原子吸收法两种方法,进行了比较。应用于土壤标准样品及样品的测定,获得了满意的结果。

This article establishes athwart aqua fortis - high chlorine - hydrofluoric acid decompose method which carry out former treatment, deuterium light emendation background flame atom absorbance analyse copper and plumbum in soil. we compare deuterium light emendation background flame atom absorbance method with extraction flame atom absorbance method we apply this method to determine soil standard and sample, and get satisfactory result.
