Electrochemical dissolution of nickel-42 in acid electrolytes

[[abstract]]©1991 Elsevier - This paper investigates the conditions for effective etching of nickel-42 in acid electrolytes such as HNO3, N2SO4 and HCL. We have found that HCl is the most suitable electroyte and the reaction orders of H+ and Cl− are 1 and 0.5 respectively when 1.0N ≦[H+]≦2.0 N and [Cl−]≦0.1 N. the anodic Tafel slope is approximately 120 mV decade−1. Finally, a reaction mechanism was proposed to describe the etching process of nickel-42 in HCl electrolyte.[[department]]化學工程學
