The present study investigated the degradation of total petroleum hydrocarbons (TPH) in crude oil polluted water using sodium persulphate as a chemical oxidant. Laboratory-scale contaminations of water and degradation experiments using 0.1 M oxidant were carried out with contact time ranging from 1 to 15 days. The TPH extraction was carried out and analyzed using gas chromatography flame ionization detector (GC-FID) (Agilent 7890A). 72% of ETPH was degraded within 15 days from an initial concentration of ~137 mg/L. Results indicated 99% efficiency in TPH degradation achieved within the first 10 days after initial contamination. Remediation technique on laboratory- and field-scale is promising and could potentially address major oil pollution contamination issues.
