ABSTRACT: Activated carbons (AC) prepared from volatile fly ash (FA) of heavy fuel oil via gasification with combined steam - CO2 was characterized and used as a low- cost adsorbent for removal of chlorophenols (CPs) e.g. 2-chlorophenol (2-CP), 4-chlorophenol (4-CP), and 2,4,6- tetra chlorphenol (TCP) in water. At pH< 2.0, maximum CPs uptake was achieved and the average half-life time (t1/2) of the equilibrium adsorption of CPs was in the range 0.80 ± 0.01- 1.1 ± 0.04 h. Data suggested use of AC in packed column for separation and determination of various concentrations (0.5-100 µgL-1) of CPs in water (0.5-1.0 L). Complete extraction and recovery (97.4 + 2.9 %, n=5) of CPs were achieved at 2 mL min-1 flow rate. Analysis of CPs spiked onto tap- and seawater were also analyzed by AC packed column and the results were compared with the standard HPLC method at 95% confidence (P-0.05, n=5). The experimental student t test (texp 1.81-1.93) and F (Fexp 1.21-5.76) values were lower than the tabulated t (tcrit. = 2.78) and F (6.38), respectively. AC packed column provides remarkable selectivity, reproducibility, and cost-effectiveness towards removal and/ or determination of CPs. AC adsorbent may serve positively in point-of-care use.
