We studying in this research the reaction with Cadmium
sulphate in an aqueous solution by physical - chemical method in
presence of MaleicAcid , and determined compounds which are
formed in this solution and we calculated of it formation the
cons
tants.
After we used these electrolytes in plating by Cadmium ,
that is by electro precipitation of this metal on the solid electrodes
(steel, copper) so that we definite the best of these electrolytes for
galvany and the set necessary conditions for its use.
Pollution by heavy metals, due to their toxic nature and other adverse
effects, is one of the most serious environmental problems. Many heavy metal
ions, such as mercuric ions are detected in industrial wastewaters originating
from metal plating,
mining activities, paint manufacture, etc. This ion isn’t
biodegradable and tends to accumulate in living organisms, causing various
diseases and disorders. Therefore, it should be removed from aqueous solution
before discharge.
