摘　　要：本文研究了在柠檬酸介质中，痕量钒催化溴酸钾氧化灿烂绿褪色的新指示反应，建立了一个测定痕量钒的新方法．线性范围为００２—０．１０μ２５ｍｌ和０１２—０．３３μｇ／２５ｍｌ，方法灵敏度为６．４３×１０－１１ｇ／ｍｌ．用于人发、水样品中机的测定，结果满意．n this paper,a new method has been developed for determination of trace vanadium,which is based on citric acid,using a new indicator that vanidium catalytic potassium bromate oxidizats brillant green and decolours it.The range of liner is 0.02-0.10μg/25ml and 0.12 0.33μg/25ml.The limit of detection is 6.43×10-11g/ml.lt is satisfactory to apply this method to the allalysis of water and human hair samples.
