Abstract

The possibility of photometric determination of rhenium content in alloys based on titanium reagent thiourea is hereby investigated. The developed method is based on a translation of the sample in a solution mixture of hydrofluoric and nitric acids. The molybdenum which prevents the reaction of formation of colored rhenium complex with thiourea binds to calcium oxide. The rhenium content is determined by the calibration curve. The developed method does not require the use of toxic reagents, is more selective and accurate in comparison with previously existing methods. Analysis time is reduced by 2–3 times to 60 minutes. As a result of this work a photometric method for the determination of rhenium from 0,05 to 1% by weight with thiourea in complexly titanium alloys is developed. The error in determining the rhenium content is 5% (rel.).
