AB  - A series of experimentswere conducted to examine the effect of citric acid on the dissolution ofzerovalent zinc. The effects of citric acid concentration, the presence ofanions and temperature were studied. The results have shown that zincdissolution registered a maximum of 34% with 0.5M citric acid after 270 min andthat the nature of anions present with citric acid affected differently thedissolution rate. In fact, the presence of 2M nitrates with 0.5M citric aciddissolved totally zinc after 30min while 91.85% and 13.15% were dissolved inthe presence of 2M chlorides and sulfates respectively after 270min. SEManalyses have shown that the morphology of the corroded surface depended on thecomposition of the solution. The kinetic study has shown that zinc dissolutionwas controlled by the chemical reaction in all cases and that the activationenergy was 39.3 kJ mol-1.
