ADSORPTION OF METHIONINE ON MILD STEEL

The adsorption of methionine at the mild steel surface from acidic solutions is studied using gravimetric technique. The adsorbability of methionine (values of surface coverage) depends on the nature of the acid and the concentration of methionine. The surface coverage with the adsorbed methionine i...
