Application of Organic Reagents for the Spectrophotometric Determination of Micro Amounts of Rhenium

A review with 97 references on the application of 48 organic reagents for the spectrophotometric determination of micro asmount of rhenium is presented.The reagents introduced in this paper classified into four main groups,namely,organic dysestuffs,oximes,stlfur- containing reagents and are various miscellaneous reagents.The optimum conditions for the development of colouration,spectrophotometric characteristics of the rhenium complex and adherence to Beer's law or limits of detection given for each reagent as well as interfering ions for some reagents are listed in details in four tables. Hence,the paper has well revealed a general aspect of the research work for the spectrophotometric determination of micro amounts of rhenium using organic chromogenic reagents during past twenty years.
