Electrochemical recovery of nickel and cadmium from spent Ni-Cd batteries [articol]

Abstract

In compliance with Directives 91/157/CEE and 91/338/CEE about spent batteries with dangerous, the paper proposes some laboratory electrochemical methods for valuable metals recovery like Ni and Cd from Ni-Cd spent batteries. The paper describes quick analyses and control methods for Ni and Cd, by AA spectroscopy, carried out on a novAA 400 G atomic absorption spectrometer - Analytik Jena, with graphite oven, with WinAAS 3.17.0 software for evaluation, control and result presentation, a so-called cookbook, for every element, and a HS 55-1 hydride generator. The components of the deposits were determined by SEM-EDAX electron microscope Inspect S - FEI-Holland.
