Descripción
The present work studies the efficiency of alkaline activated persulfate (PS) to remediate an aged diesel fuel contaminated soil from a train maintenance facility. The Total Petroleum Hydrocarbon (TPH) concentration in soil was approximately 5000 mg kg?1 with a ratio of aliphatic:aromatic compounds of 70:30. Aromatic compounds were mainly naphtalenes and phenanthrenes. The experiments were performed in batch mode where different initial concentrations of persulfate (105 mM, 210 mM and 420 mM) and activator:persulfate ratios (2 and 4) were evaluated,with NaOH used as activator. Runs were carried out during 56 days. Complete TPH conversion was obtainedwith the highest concentration of PS and activator,whereas in the other runs the elimination of fuel ranged between 60 and 77%. Besides, the abatement of napthalenes and phenantrenes was faster than aliphatic reduction (i. e. after 4 days of treatment, the conversions of the aromatic compoundswere around 0.8meanwhile the aliphatic abatementswere 0.55) and no aromatic oxidation intermediates fromnaphtalenes or phenantrenes were detected. These results show that this technology is effective for the remediation of aged diesel in soil with alkaline pH
