Resumo(s)
The recovery of metal ions by electrodeposition from solutions resulting from
the lixiviation of spent Zn-MnO2 batteries was studied. It was attempted to
optimise the electrodeposition process, the selectivity of ion-separation, the
morphologic characteristics, and the anticorrosive and galvanic properties of
metallic deposits. The simultaneous deposition of zinc and manganese on
different ferrous substrates under various experimental conditions was tested.
This allowed us to access the efficiency of the electrodeposition, the morphology
and composition of the metallic deposits, as well as their performance as
galvanic coating layers. The effect of amine additives, namely, of methylamine
and ethylenediamine, on the properties of the coatings was also studied. It was
shown that the amines with buffering or passivating effects improve the
simultaneous deposition of Mn.
