@article{J. DUGAN_NEGRÃO_2013, title={SUSTAINED-RELEASE PERMANGANATE (REMOX® SR ISCO REAGENT) AND PERSULFATE FOR PASSIVE TREATMENT OF CHLORINATED SOLVENTS AND EMERGING CONTAMINANTS}, url={https://aguassubterraneas.abas.org/asubterraneas/article/view/27540}, abstractNote={<p>A sustainable, simple, and low O&M approach has been developed using<br />innovative oxidation chemistries in concert with innovative slow-release deployment<br />strategies to achieve passive, cost-effective treatment of large chlorinated solvent and<br />emerging contaminant plumes. This novel remedial technology involves oxidants in the<br />form of sustained-release permanganate and sustained-release persulfate. Paraffin wax is<br />used as the environmentally benign and biodegradable matrix material for encapsulating<br />solid potassium permanganate (KMnO4) or sodium persulfate (NaS2O8) particles.<br />Sustained-release (SR) oxidants contain ~80% permanganate or unactivated persulfate<br />and can be formed as cylinders for direct push applications, inserted into holders for<br />emplacement in permanent or temporary wells. The material may also be chipped/cubed<br />for hydro-fracturing into low permeability media for treating back diffusion of organic<br />contaminants. This presentation will provide the results of a variety of experimental and<br />modeling efforts as well as preliminary results from RemOx® SR ISCO Reagent pilot-scale<br />field studies.</p>}, journal={Águas Subterrâneas}, author={J.
