Abstract

Present study deals with the adsorption of glycolic acid (GA) from aqueous solutions by using a mixture of adsorbents of clay and charcoal. Recovery process depends on contaminated water that obtained from scientific research laboratories and drug manufacturing plants, with adsorption technology via using activated carbon adsorbent with a new natural adsorbent that collected from dust storms. Thermodynamic parameters (-ΔGo, -ΔHo and -ΔSo) and the isotherms were correlated with a model based on the principle of phase equilibrium..
