本文采用一种新的思路，较详尽地研究了用Ｎ＿２Ｏ－Ｃ＿２Ｈ＿２ＦＡＡＳ法测定土壤中痕量钒时，共存组合对Ｖ的干扰作用，并在此基础上探讨了主要干扰组合对Ｖ的原子吸收信号产生干扰的作用机理。为消除干扰提供了依据，同时，为研究土壤中Ｖ的背景奠定了必要的基础。
In this paper, a new idea is adopted to study the interference effect of coexistence on V when N-O-C 2 H 2 FAA method is used to determine trace vanadium in soil. On this basis, the effects of main interference combinations on atomic absorption of V The mechanism of interference. Provided the basis for eliminating the interference, and laid the necessary foundation for studying the background of V in soil.
