摘　　要：研究了痕量钒（ｖ）催化氯酸钾氧化二苯胺磺酸钠形成紫色产物的新指示反应，确定了测定痕量钒的适宜条件，它的最大吸收波长为５６０ｎｍ，灵敏度为９×１０￣（－１１）ｋｇ／Ｌ，测定范围０～０．０２ｍｇ／Ｌ，本文研究了此法在茶枯和人发中痕量钒测定中的应用。The V(v)catalytic effect on the colour reaction,in which the sodium diphenylaminesulphonic acid salt was oxidized by KClO_3 forming purple product,was examined in detail.The optimum conditions for determining V(V)were established.The max absorption was560 nm,the sensitivity of determination was 0～0.02 mg/L,This method has been used indeterming the trace amount of V(v)in hair and cake of oil-tea camellia.
