HEXAMINE AS CORROSION INHIBITOR FOR ZINC IN (HNO3 + HCL) BINARY ACID MIXTURE

The corrosion of zinc in binary acid mixture (HNO3 + HCl) containing Hexamine has been studied at different acid concentrations, inhibitor concentration and temperatures. As the concentration of acid increases corrosion loss and I.E. (Inhibition efficiency) increases. As the concentration of inhibitor increases I.E. also increases. As temperature  increases  corrosion loss increases while percentage of I.E. decreases.
