Abstract

A new reagent, bis-3,3'-(5,6-dimethyl-1,2,4-triazine), BDMT, is proposed for the colorimetric determination of copper. The reagent is water soluble and is easily prepared in the laboratory. An intensively colored orange complex, Cu(BDMT)2+1, is formed upon reaction of copper(I) ion and the reagent in aqueous solution at pH 5.0. The complex exhibits a wavelength of maximum absorption at 444 mμ with a molar absorptivity of 9,700. The perchlorate salt of the complex is readily extracted into nitrobenzene from aqueous solution. A proposed spectrophotometric method for the determination of copper is both accurate and precise.
