Effect of Persulfate Formulations on Soil Permeability
by MIAO YU, M.S. Washington State University August 2010 Chair: Richard J. Watts In situ chemical oxidation (ISCO) using persulfate is a promising technique for the remediation of soil and groundwater contaminants. Persulfate activated by iron (III)-EDTA or sodium hydroxide can accelerate the degradation of contaminants. However, in previous studies of ISCO remediation processes, the applicatio...
متن کاملPersulfate Transport in Two Low-permeability Soils
by MARISSA C. MERKER, M.S.C.E. Washington State University August 2010 Chair: Richard J. Watts Persulfate is a promising in situ chemical oxidation treatment (ISCO) for the remediation of low-permeability strata because it is more stable in the subsurface and can rapidly degrade recalcitrant contaminants compared to other technologies. ISCO technologies include catalyzed hydrogen peroxide propa...
متن کاملPersulfate Activation by Major Soil Minerals
by MUSHTAQUE AHMAD, M.S. Washington State University December 2008 Chair: Richard J. Watts Oxidant interaction with subsurface materials is a major factor influencing the effective application of in situ chemical oxidation (ISCO) for contaminant destruction. The newest and least explored ISCO oxidant source is persulfate. Persulfate interaction with subsurface minerals was investigated as a bas...
متن کاملOxidative Degradation of 2-chlorophenol by Persulfate
The degradation of 2-chlorophenol (2-CP) by persulfate was investigated. The kinetics of persulfate oxidation of 2-chlorophenol in aqueous solutions at various pH, oxidant concentration, temperature, Fe2+ and Cu2+ ions content was studied. Maximum of 2-CP degradation occurred at pH 8. The oxidation rate of 2-CP increased with increasing the persulfate molar excess. The degradation process was s...
متن کاملDetermination of total nitrogen in aqueous samples using persulfate digestion
Determination of total nitrogen in aqueous samples after potassium persulfate digestion compared favorably in both precision and nitrogen recovery with determinations obtained using Kjeldahl digestion. The determination of total nitrogen (TN = inorganic and organic fixed nitrogen) has largely depended either on acid Kjeldahl digestion ( cf. Strickland and Parsons 1972) or on photo-oxidation (Ar...
