Abstract:In the presence of polyethyl alcohol, the coloring reaction conditions of ReO4ˉ - Ethyl violet - Polyethyl alcohol have been studied, a novel ,way to directly determine Rhenium(Ⅶ ) have been established. The lincar range of the determination is 0. 0 - 10.0μg/10mL. Regression equation is A = 0. 0729Cμg/10.0mL - 0.0001. A molar absorptivity of it is 1.36 × 105 L/mol^-1 cm^-1. Limit of detection is 1.4 × 10^-3μg/mL. In the presence of fight quantity citric acid or tartaric add, molybdenum and tungsten do not interfere detection. The way is used to determine trace rbenium in flue dust, molybdenum trioxide and molybdenum mine. The recovery is 97.0- 100.6%. We can also obtain a satisfactory result.
Keywords:rhenium( Ⅶ )  micellte  photometric
