Description Copper is extracted at pH 5.5 with 3 x 10(-4) M cryptand 222 in dichloromethane with 3 x 10(-4) M erythrosine B as the counter-ion. It can be stripped with 0.5 M perchloric acid and determined by atomic absorption spectrometry at 324.7 nm. Copper has been separated from multicomponent mixtures containing zinc, mercury, iron, cobalt, nickel and manganese, which are generally encountered in environmental samples.
