Abstract

The purpose of this project was to compare the effectiveness of different polymers used in biodegradable Controlled-Release Oxidation Pellets. Controlled-release pellets are used to administer an oxidant encapsulated in a polymer in which the polymer releases the oxidant through its permeable membrane over time opposed to all at once. This method can be used to treat wastewater over time in a way that does not disturb vegetation and has no adverse effects on the water itself. For this project, the polymers chosen were Polyvinyl acetate(PVAc) and a mixed polymer makeup of poly (ethylene oxide) (PEO) and Polycaprolactone (PCL). The oxidant chosen to be observed was Potassium Permanganate, KMnO4. Together, the KMnO4 and the chosen polymers remediates bacterial contamination as well as hydrocarbon contamination. in water. This method was analyzed by measuring the absorbency and concentration of the oxidant released from the pellets in deionized water over a time span of three hours and at 24 hours.
