| 摘 要： | 在自行研制的一套流动注射分析装置上,实现了导数光度法测定金属矿样中钒含量。利用二安替比林基-(对二甲氨基)苯基甲烷与钒显色的适宜条件(λm ax=552 nm),一次注样产生两个拐点导数光度值(△A),进样频率为110次/h,钒含量在0~0.18μg/mL符合比尔定律。方法操作简单,用于矿石和炉渣样品中痕量钒的测定,结果令人满意。

| Abstract: | The paper presents the determination of trace vanadium in ore samples by derivative spectrophotometry,based on the chromatogenic rection of diantipyryl-(p-dimethylamino)-phenylmethane(DADM) with vanadium(λmax=552 nm),in a homemade flow injection system.Two inflexion points of the derivative absorbancy(△A) could be obtained in one injection.The method provides linear dynamic range of 0～0.18 μg/mL for vanadium with sampling frequency of 110 injections per hour.The method has been applied to the determination of trace vanadium in ores with satisfactory results. |
