This study investigated the adsorption potential of oil palm shell-based activated carbon to remove 2,4,6-trichlorophenol from aqueous solution using fixed-bed adsorption column. The effects of 2,4,6-trichlorophenol inlet concentration, feed flow rate and activated carbon bed height on the breakthrough characteristics of the adsorption system were determined. The regeneration efficiency of the oil palm shell-based activated carbon was evaluated using ethanol desorption technique. Through ethanol desorption, 96.25% of the adsorption sites could be recovered from the regenerated activated carbon.
本研究使用固定床吸附柱，研究了油棕壳基活性炭从水溶液中去除2,4,6-三氯苯酚的吸附潜力。测定了2,4,6-三氯苯酚入口浓度、进料流速和活性炭床层高度对吸附系统穿透特性的影响。采用乙醇解吸技术评估了油棕壳基活性炭的再生效率。通过乙醇解吸，再生后的活性炭可回收96.25%的吸附位点。
