Persulfate Oxidation for the Remediation of Petroleum Hydrocarbon-Contaminated Soils
The feasibility of total petroleum hydrocarbon-contaminated (TPH) soil remediation was studied using persulfate oxidation. Factors tested included type of activator, persulfate concentration, number of persulfate applications, and reaction time. Probe chemicals were used to study effi ciency of the persulfate oxidation mechanism. The best activation method used Fe2+, which achieved 40.8% TPH de...
متن کاملDefluorination of Aqueous Perfluorooctanesulfonate by Activated Persulfate Oxidation
Activated persulfate oxidation technologies based on sulfate radicals were first evaluated for defluorination of aqueous perfluorooctanesulfonate (PFOS). The influences of catalytic method, time, pH and K2S2O8 amounts on PFOS defluorination were investigated. The intermediate products during PFOS defluorination were detected by using LC/MS/MS. The results showed that the S2O8 (2-) had weak effe...
متن کامل2-Chlorophenol Removal of Aqueous Solution Using Advanced Oxidation Processes Resulting from Iron/ Persulfate and Ultra Violet/ Persulfate
Background: Advanced oxidation processes are used to remove toxic aromatic compounds with low biodegradability, such as 2-chlorophenol. This study investigates the use of Sulfate (SO4-) and persulfate (S2O82-) radicals, as one of the advanced oxidation methods, to remove 2- chlorophenol from aquatic solutions. Materials and Methods: This experimental and pilot-scale study was carried out usi...
متن کاملHomogeneous and Heterogeneous Photocatalytic Water Oxidation by Persulfate.
Photocatalytic water oxidation by persulfate (Na2 S2 O8 ) with [Ru(bpy)3 ](2+) (bpy=2,2'-bipyridine) as a photocatalyst provides a standard protocol to study the catalytic reactivity of water oxidation catalysts. The yield of evolved oxygen per persulfate is regarded as a good index for the catalytic reactivity because the oxidation of bpy of [Ru(bpy)3 ](2+) and organic ligands of catalysts com...
متن کاملRemediation of total petroleum hydrocarbons using combined in-vessel composting and oxidation by activated persulfate
This study was investigated the efficiency of activated persulfate and in-vessel composting for removal of total petroleum hydrocarbons. Remediation by activated persulfate with ferrous sulfate as pre-treatment was done at batch system. In the chemical oxidation, various variables including persulfate concentrations (10-3000 mg/g as waste), ...
