摘要：

In this work, cadmium from spent Ni-Cd batteries is recycled. Ionic cadmium is recovery from acidic solution using a galvanostatic technique. Electrodeposition charge efficiency and deposit morphology depend on current density. Charge efficiency reaches up to 85.0% for a current density between 5.0 and 10.0 mA cm(-2) and decreases with the increase in current density. Pore size decreases with the increase in current density. (C) 2004 Elsevier B.V. All rights reserved.
