Optimization of Process Parameters for Adsorption of Phenol from Aqueous Solution Using Unripe Plantain Peels Activated Carbon

The study investigated the optimum conditions for adsorption of phenol from aqueous solution using plantain peels activated carbon. Low-cost adsorbents were produced unripe peel by both physical and chemical activation processes at carbonization temperature 400oC 2 hrs. unwashed carbon (UPPAC) was with ZnCl2 impregnation ratio 1:2 while (NAPPC) not impregnated any chemical. carbons characterized in terms surface area, porosity, iodine number, ash content, yield pH. result showed that physicochemical properties UPPAC significantly higher than those NAPPC having area 957 m2/g, porosity 32.2%, number 736 mg/g, content 9.02% 65%. based on three variables, contact time, adsorbate concentration A total 27 experimental runs used to effects these parameters response methodology (RSM) as design. batch found increase initial time but decreases achieved percentage removal 91% 21 mg/g its pH dependent (pH 2), better acidic conditions. amount adsorbed also increased until equilibrium reached 150 mins. Thus, chemically can be solution.
