Spectrophotometric Determination of Uranium without solvent extraction in Geomaterials using Arsenazo-III in presence of EDTA
Authors(4) :-Satya Prakash, Vijay Kumar, Smeer Durani, S. Thangavel
A sensitive and selective spectrophotometric method for the determination of uranium ranging from 100µg to 4000µg U3O8/g of geomaterials (more than 4000µg U3O8/g of geo- materials is also possible by sub-dilutions), using disodium salt of ethylene diamine tetra-acetic acid (EDTA) and colour development with 2,7-bis(2,2-arseno phenyl azo) 1,8-dihydroxy naphthalene-3,6-disulphonic acid (Arsenazo-III) in phosphoric acid medium at λmax~642 nm was developed. Method is basically direct determination of uranium in coloured solution and it does not require solvent extraction for the removal of interferences, however, stoichiometry of the reagents solution is to be followed as per the optimised conditions.
