Optimization of Process Parameters for Adsorption of Phenol from Aqueous Solution Using Unripe Plant

The study examined the optimum environments for the adsorption of phenol from aqueous solution utilizing plantain peels activated element. Low-cost adsorbents were produced from raw plantain peel by both physical and synthetic activation processes at carbonization hotness of 400oC for 2 hrs. The chemical mobilized unwashed element (UPPAC) was activated accompanying ZnCl2 at impregnation ratio of 1:2 while the tangible activated element (NAPPC) was not impregnated accompanying any chemical. The created carbons were characterized in agreements of surface area, porosity, iodine number, ash content, element yield and pH. The result showed that the physicochemical characteristics of UPPAC were significantly above those of NAPPC having surface area of 957 m2/g, porosity of 32.2%, iodine number of 736 mg/g, ruins content of 9.02% and carbon yield of 65%. The best conditions for the adsorption of phenol from the liquid solution using UPPAC was established three variables, contact time, adsorbate aggregation and adsorbate pH. A total of 27 experimental runs were used to study the effects of these limits using the answer surface methodology (RSM) as the exploratory design. The result of the batch adsorption was found to increase accompanying initial adsorbate aggregation and contact time but decreases accompanying increase adsorbate pH. UPPAC achieved optimum allotment removal of 91% at beginning phenol concentration of 21 mg/g and its evacuation was pH dependent (pH 2), better at sour conditions. The amount adsorbed more increased with contact opportunity until balance was reached at 150 mins. Thus, chemically stimulated unripe plantain peel can be secondhand for the removal of phenol from liquid solution.
