摘要：

A sensitive procedure for spectrophotometric determination of V(V) with pyrocatechol and N1-hydroxy-N1,N2-diphenylbenzamidine (HDPBA) is described. The value of molar extinction coefficient (epsilon) of the colored complex in chloroform is 5.60 x 10(5) dm3 mol-1 cm-1 at lambda-max 410 nm. The optimization of analytical variables, effect of diverse ions and application of the method to environmental samples have been investigated.
