摘要
本文较详细地研究了在Fe、Co基体中测定铬时出现的与浓度有关的化学干扰,铬的价态对干扰的影响,并讨论了干扰的机理及克服干扰的办法。
In this paper, chemical interference with relation to the concentration and influence of thevalence of chromium on the interference have been studied in datail when chromium was deter-mined in iron and cobalt matrix by air-ethyne flame. Machanism and method of eliminating in-terference were discussed.
