Abstract: The present invention involves a persulfate-release material used in the filler of permeable reactive barrier (PRB). This material presents double-layered structure characteristic: inner- and outer-layers are consisted of persulfate, cement, sand and water with different mass ratio. Two different types of moulds are used for the regulation of the shape of the two-layer structures, which guarantees the stability and reproducibility of its structures and properties. During the whole released process, the released rate become more uniform and stable by the use of this material. During the whole service period, the change of the released rate is very slow, and the service lifetime can be 1-10 years. This invention can both reduce the initial released rate and improve the later released rate, and thus the whole released rate can be more uniform, which can be an important method to promote the efficiency of the persulfate toward engineering application.
