Use of variamine blue as a chromogenic reagent for rapid spectrophotometric determination of nano amount of chromium

Trace amounts of Chromium have been determined using a newly developed simple, rapid and sensitive spectrophotometric method. Variamine blue is used as a chromogenic reagent and the proposed method is based on the reaction of chromium(VI) with potassium lodide in acid medium to liberate iodine that...
