Controlled Release Chemical Oxidation: Sodium Persulfate Encapsulated In Pvac Polymer, Mosarrat Samiha Kabir
Theses
In this study, sodium persulfate was encapsulated in polyvinyl acetate (PVAc) polymer to investigate the potential of activated persulfate to remediate total coliform and E. coli bacteria from contaminated water through a control release system. Controlled release structures were produced with the polymer and persulfate melted to form pellets at two different baking times. CRP structures containing 60 weight % sodium persulfates blended with 40 weight % polyvinyl acetate (PS- PVAc) were baked for 4 minutes and 10 minutes at 120ºC. The kinetics release of sodium persulfate was studied in a water system and in sand columns. Experimental results showed …
