摘　　要：本文根据一定的实验结果,对N_2O-C_2H_2FAAS测定土壤中的痕量铍时有关干扰作用的机理作了初步的探讨,确证了A1、Ti、Ca等对Be的干扰系凝固相化学干扰.In this paper, on the basis of Some of the experienment results, Mechanism of relative interferences when determined in trace amounts of Beryllium by N2O-C2H2 Flame Atomic Absorption Spectroph-otometry ( FAAS ) in soil is studied primarily. It is proved the Aluminum,Titanium and Calcium etc.i nterference with Bergllium is chemical-interference in condensed phase.
