| 摘 要： | 应用双波长标准加入法，以５－Ｂｒ－ＰＡＤＡＰ为显色剂，同时测定了铬和钒。选择钒等吸收点波长５９３ｎｍ、６１７ｎｍ为测定波长。钒含量回归方程为Ｃ＝０．１２４４＋４０．４１Ａ．相关系数Ｒ＝０．９９９９。将此法用于合成样品分析，结果满意。

| Abstract: | In this paper, the dual-wavelength standard addition method has ben applied to simultaneous determination of chromium and vanadium with 5-BrPADAP. Two wavelengths at identical absorption points of vanadium, 593nm and 617 nm have been selected as the measuring wavelengths. The linear regression equation of vanadium content is C= 0.1244 + 40.41A and the correlation coefficient R = 0. 9999. By this method, chromium and vanadium in synthetic samples are determined simultaneously with satisfactory results. |
