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), ...
The kinetics of the reaction between Iäaq and S^O^g has been studied under conditions of production of iodine at a known rate by the persulfate-iodide reaction and its consumption by 5..03 . The effective concentration of iodine during the steady state is measured from its reduction potential at a bright platinum foil electrode. The reaction is of first order with respect to I3~ and 5..03 indiv...
The use of heat-activated peroxymonosulfate oxidation for the degradation antibiotic compound sulfamethoxazole (SMX) was studied in this paper. It found that process follows a pseudo-first order kinetic model. Increasing oxidant concentration and/or activation temperature led to higher efficiency. pH from 3 9.5 resulted efficiency as well, although SMX significantly inhibited at 11. Through rad...
The impact of chemical on the native microbial population during in situ chemical oxidation (ISCO) is not well understood. As a result, some concerns exist within the remediation community as to the potential of negative impacts ISCO may have on bioremediation processes, especially its impact on down-gradient plume control via bioremediation and its impact on subsequent natural attenuation proc...
In this study, a nickel ferrite (NiFe2O4) system was constructed to purify phenol solution in water. During the process, influences of several critical operating parameters including NiFe2O4 amount, PS dosage, MW power, initial pH value, and different natural water anions were systematically studied. The results indicated that performed excellently regarding removal efficiency (97.74%) within 3...
