计算原子吸收法间接测定钒

INDIRECT DETERMINATION OF VANADIUM BY COMPUTATIONAL FLAME ATOMIC ABSORPTION SPECTROMETRY

本文研究了用空气－乙炔火焰原子吸收法间接测定帆的一种计算分析方法，利用钒对原子吸收法测定铬时的干扰效应，以多项式作为表达其干扰效应的数学模型。在已知铬含量的铬钒混合液中测定铬的吸光度，并从数学模型中解出钒的浓度，从而间接测定了钒。

This paper describes a computational analysis method for indirect determination of vanadium by air--acetylene flame atomic absorption spectrometry.The method is based on the interferent effect of vanadium on chromium which can be described in terms of a multinomial. Once the absorbance of chromium in unknown vanadium solution, in which the content of chromium is known, has been determined, the concentration of vanadium can be calculatied from the multinomial.
