Abstract
Many organic compounds have been generated due to the increasing industrial activities in the world. In Situ Chemical Oxidation (ISCO) is one of the most popular technologies used for soils and water remediation. The most common system used for remediation is modified Fenton's reagent, or catalyzed hydrogen peroxide propogation (CHP). Because this system's reactions provide different oxygen species, efficient treatment will be achieved due to using it. Superoxide is one of the oxygen species that is generated in CHP system, and also in other systems, such as a base-activated persulfate system. It is a species responsible for enhanced degradation of organic chlorinated contaminants, desorption of sorbed contaminants, and destruction of dense non-aqueous phase liquids (DNAPLs) organic contaminants. Since the generation of superoxide in several systems has one or more limitations, bicarbonate-activated hydrogen peroxide (BAP) technology has been created to generate efficient superoxide. In this thesis, the BAP system is used to generate the most efficient superoxide. Nitrotetrazolium blue chloride (NBT) is used as probe compound to detect superoxide; Nitrobenzene (NB) is used as probe compound to detect a hydroxyl radical.
