Talanta, 1996•Elsevier3-Hydroxy-2-methyl-1, 4-naphthoquinone-immobilized silica gel has been used for the
adsorption and estimation of copper, cobalt, iron and zinc by both batch and column
techniques. The distribution coefficient D determined for each metal ion was as follows (ml
g1): Fe, 3.6× 102; Cu, 3.9× 102; Co, 3.8× 102; Zn, 4.1× 102. Methods have been developed
to estimate zinc, copper and cobalt in milk, steel and vitamin samples respectively.
