Analytical Applications of Mixed Ligand Complexes. II. Separation-Gravimetric Determination of Cu(II) as Its Mixed Ligand Complex with 1,10-Phenanthroline and p-Cresotic Acid

Abstract

A method is presented for the gravimetric determination of Cu(II) followed by its separation from Ni(II), Co(II), Mn(II), and other anions and cations by precipitating it as its mixed ligand complex with 1,10-phenanthroline and p-cresotic acid (5-methylsalicylic acid). The precipitate is equivalent to 0.184 times its weight of copper. The method has potential for use in the large-scale separation of copper.
