【摘要】 基于铁（Ⅲ）和钒（Ⅴ）对溴酸钾氧化维多利亚天蓝Ｂ褪色的催化作用及在不同反应条件下二者催化作用的差异，以反应条件作为化学计量学中的量测通道，应用ＣＰＡ矩阵法对铁（Ⅲ）和钒（Ⅴ）同时测定进行了研究，建立了流动注射催化光度法同时测定铁和钒的方法．在铁（Ⅲ）和钒（Ⅴ）浓度比为１∶２０～４０∶１的范围内，应用该法对其混合物进行测定，回收率分别为９５．５％和１０３．５％．更多还原

【Abstract】 A flow injection catalytic spectrophotometry is described for the simultaneous determination of iron(Ⅲ) and vanadium(Ⅴ).It is based on the different catalytic behavior of iron(Ⅲ) and vanadium(Ⅴ) to decoloration reaction between potassium bromate and victoria blue B in different media and chemometric method CPA metrix is employed. This method has been appllied to determination of iron(Ⅲ) and vanadium(Ⅴ) binary mixture,in the range of 1∶2～40∶1 (concentration ratio),with the average recoveries of 95.5% and 103.5% respectively for iron(Ⅲ) and vanadium(Ⅴ).更多还原
