Abstract
Because of the increasing use of surfactant, a study on the effect of a surfactant on the degradation of organic compound such as trichloroe thylene (TCE), which is often detected in contaminated groundwaters, i s needed. The objectives of this study were to determine biokinetic co nstant of TCE and to investigate the TCE degradation in presence and a bsence of a biodegradable nonionic surfactant, with phenol-oxidizing m icroorganisms. In a batch experiment, phenol provided a carbon and ene rgy source to the phenol-oxidizing microorganisms that could produce m ore requisite enzyme capable of TCE degradation. The pseudo first-orde r rate constant (k) of TCE was found to be 0.0089 L mg(-1) VS-day. Mor e phenol was degraded in the absence of surfactant than in the presenc e of surfactant. The surfactant was also degraded by the phenol-oxidiz ing micrrorganisms. In the batch study, the addition of the surfactant (50 mg L-1) neither improved nor significantly hindered the TCE degra dation.
