N_2O－C_2H_2火焰原子吸收法（FAAS）测定土壤中痕量钒—有关干扰作用

Determining Trace Amount of V in Soil by N_2O-C_2H_2FAAS on influences and its mechanism

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 thinking is adopted in studying more entirely interferences caused by co-existing component with V in soil by means of N_2O-C_2H_2 FAAS, and on the basis of it mecha-nism of interferences is analysed and discussed. The evidence for eliminating inferferences is pro-vided. Meanwhile,it is necessary basis for studying background value of V in soil.
