摘要

Abstract

Extracts of elephant grass (

Pennisetum purpureum

) blended with some intensifier halides like ammonium chloride (AMC) and potassiumiodide (PTI) were investigated as corrosion inhibitor formild steel. The corrosion processwasmonitored in 3.5% HCl bymass loss and electrochemical techniques at 30

60 and 90℃. Addition of AMC and PTI increased the inhibition efficiencywith the highest inhibition efficiency obtainedwith PTI blended extract. The blends behaved as mixed type inhibitors and were spontaneously adsorbed onmild steel surface in exothermic nature. Synergistic parameters of the intensifier ions revealed cooperative effect. Kinetic data treatment indicated increase in energy barrier by intensifier ions. The results demonstrate that elephant grass extract blended with halide ions can act as alternative ecofriendly inhibitor for mild steel at elevated temperatures.
