Sodium percarbonate was encapsulated in poly(vinylidene chloride) to determine its potential as a slow-release oxygen source for biodegradation of contaminants in subsurface soils. In laboratory studies under aqueous conditions, the encapsulated sodium percarbonate was estimated to release oxygen over about a two-month period. Microbial survival in the persence of encapsulated sodium percarbonate was markedly increased compared to the unencapsulated compounds. In laboraotry studies, the encapsulated sodium percarbonate was used to provide oxygen as an electron acceptor for microorganisms during the biodegradation of propylene glycol.
