• Description: Electrooxidation and electroreduction of Ni and its ions was object of many studies. In these studies many resction mechanisms were supposed. In our contribution the electrolytic deposition of Ni from solutions with NiSO4, H3BO3 and NaCl was studied by cyclic voltammetry and elimination voltammetry with linear scan (EVLS) The effect of pH and composition of electrolytes on electrode process was observed. CV and Using the results of EVLS, adsorptions, formations of intermediary products, reactions on electrode surfaces were discussed.
