Liquid-liquid extraction of copper(II) with cyclic and acyclic tetrathioethers

The liquid-liquid extraction of copper(II) with cyclic and acyclic tetrathioethers (L) into 1,2-dichloroethane was examined. When hexanitrodiphenylamine ion (A −) was used as the counter anion, the extracted species [Cu(II)L(OH)] + A − was predominant at pH > 6.0. The logarithmic extraction const...
