A study of the interaction between rhenium(VII) and allylthiourea by spectrophotometry Chemistry

Abstract

The possibility to obtain a complex compound of the rhenium(V) with allylthiourea has been studied. The optimal conditions, in which the chemical reaction took place, have been estimated. It has been shown than this reaction may be used for spectrophotometric determination of rhenium(VII). It has been approved by means of potentiometric titration method that 1 mol quantity of tin(II) chloride is necessary to reduce 1 mol quantity of perrhenate, which witnesses about the reducing of the Re(VII) to Re(V). Allylthiourea and Re(V) form a new yellow colored complex substance having maximal light absorption at λ = 365 nm wavelength.
