Abstract

N-m-Tolyl-N-phenylhydroxylamine is proposed for the spectrophotometric determination of small amounts of vanadium. The reddish-violet complex formed with the reagent in 3-6M hydrochloric acid after extraction with chloroform shows an absorption maximum at 530 nm, and obeys Beer's law for 0-76.5 mug of vanadium in 10 ml of chloroform. The proposed method has been successfully applied to the determination of vanadium in coal and coal fly-ash.

摘要

有人提出用N-间甲苯基-N-苯基羟胺分光光度法测定少量钒。该试剂在3-6M盐酸中与钒形成的红紫色络合物，用氯仿萃取后，在530nm处有最大吸收，在10ml氯仿中，0-76.5μg钒符合比尔定律。该方法已成功应用于煤和粉煤灰中钒的测定。
