Abstract
A newly synthesized reagent, N-o-toluoyl-N-o-tolylhydroxylamine is used in a sensitive and selective spectrophotometric method for determination of vanadium(V). The method has been successfully applied to vanadium determination in Mn-Mo-Cr-V steels. The system in 2-6M hydrochloric acid medium obeys Beer's law at 510 nm in the range of vanadium concentration from 0.5 to 10.0 mug ml .
摘要
一种新合成的试剂，N-邻甲苯甲酰基-N-邻甲苯羟胺，被用于一种灵敏且选择性的分光光度法中以测定钒（V）。该方法已成功应用于锰-钼-铬-钒钢中钒的测定。在2-6M盐酸介质中，该体系在510nm波长下，钒浓度在0.5至10.0微克/毫升范围内遵循比尔定律。
