摘要
本文研究了用双波长分光光度法,以5-Br-PADAP—OP同时测定铁、镍的方法。选择522.0—584.0nm作为测定镍的波长对,选择746.0nm直接测定铁,从而消除了它们之间的相互干扰。本方法用于铝合金中铁和镍的同时测定,结果满意。
A method of dual-wavelength spectrophotometry for simultaneous determination of Fe and Ni with 5-Br-PADAP-OP is described. The dual-wavelength measurements were made with optimal wavelength pair, 522.0-584.0nm, for Ni and with a single measuring wavelength, 746.0nm, for Fe. This method has been applied to determination of Fe and Ni in aluminum alloys with satisfactory results.
