摘要
本文研究了空气－乙炔火焰原子吸收法测定铬时某些化学干扰的计算消除方法，用多项式作为表达铬和干扰元素间相互关系的函数式。经测定钴－钛，铬－铁和铬－钒干扰对混合液中铬的含量，表明计算法能较好地消除铁、钴、钒对测铬的干扰效应。
Some interferent effects of chromium determination by air-ethyne flame AAS have been eliminated by a computational method and the relationship of chromium and the interferences is described in terms of a multinomial. The experimental results of chromium determiantion in Cr-Co, Cr-Fe and Cr-V systems have confirmed that the computational correction for the interferences of Co, Fe and V to Cr is practicable.
