Possibility of Using Complexing Reagent for Processing Spent Alkaline Batteries

  • Published:
Metallurgist Aims and scope

Complex formation of sodium ethylenediaminetetraacetate (EDTA) with cadmium, iron, and nickel, whose presence is possible in starting raw material, is studied. Results obtained make it possible to use EDTA as a complexing solvent in nickel-cadmium battery processing technology.
