尿及毛发中钒的测定,可作为判断钒接触的一个指标。尿中钒的测定主要用分光光度法。此法对钒无选择性,共存的其他金属可使测定值增高。毛发中钒用放射分析测定,此法需特殊设备,故尿及毛发中钒的测定,目前尚无一般分析法。作者以前报告过,用N-肉桂酰-N-(2,3苯二甲基)羟胺(CXA)把样品中钒抽
Determination of vanadium in urine and hair can be used as an indicator of vanadium exposure. Determination of urinary vanadium spectrophotometry. This method is not selective for vanadium, coexistence of other metals can make the measured value increased. Determination of vanadium in hair by radioactive assay, this method requires special equipment, so the determination of vanadium in urine and hair, there is no general analysis. The authors previously reported that the use of N-cinnamoyl-N- (2,3-xylylene) hydroxylamine (CXA) in the sample vanadium pumping
