Since the first preparation of 1,10-phenanthroline and 2,2'- blpyrldlne by Blau, many derivatives and related compounds have been synthesized and characterized with regard to transition metal complexation. The Influence of substituents on the chromophoric properties of the ferroin and cuproine type chromogens is marked in relation to their iron and copper chelation. A recently synthesized blqulnoline derivative, 4,4'-d1hydroxy-2,2'-b1qu1nol1ne, (DHBQ), has the unusual ability to complex copper 1n strong alkali. The characteristics of the copper(I) complex, Including conditions of formation, compliance to Beer's law, and stability, are described. By use of visible and ultraviolet spectroscopy the identity of the extracted species has been deduced. A procedure for the quantitative determination of copper in trace amounts has been developed. The practical application of the recommended procedure is shown by the successful determination of copper in the alkali metals, sodium and potassium.
