Yang, Jung-Seok Baek, Kitae Kwon, Tae-Soon Yang, Ji-Won 2024-01-20T20:30:27Z 2024-01-20T20:30:27Z 2021-09-05 2009-11-25 1226-086X https://pubs.kist.re.kr/handle/201004/131954 The adsorption characteristics of chlorinated solvents, trichloroethylene (TCE) and perchloroethylene (PCE), in surfactant solutions with granular activated carbon (GAC) were investigated with the goal of recovering the surfactant from the effluent in surfactant enhanced remediation (SER). Triton X-100 (TX100) and X-165 (TX165) were selected as model surfactants, and the GAC was Darco 20-40. The adsorption amounts for the TX100 and TX165 onto GAC was about 0.26-0.27 g/g GAC. On a GAC fixed bed, the adsorbed amounts of TCE (0.19 g/g) and PCE (0.35 g/g) in the TX165 (10g/L) solution onto the GAC were higher than those for TCE(0.16 g/g)and PCE (0.24 g/g) in the TX100 (10 g/L) solution. Because the ratio of surfactants/chlorinated solvents in the ordinary effluent of SER is higher than 1, activated carbon adsorption could be used as an alternative of post-treatment method in SER.
