Abstract: At present, the organic pollutions of groundwater is becoming more and more serious. Traditional in-situ remediation technologies can not always reach the expectations for theirs reverse diffusion and low remediation efficiency. Controlled release technology can reduce the release rate and prolong the release time of reactive components, which has attracted extensive attention in the remediation of groundwater organic pollution. In this paper, the preparation and application of controlled-release materials are reviewed and summarized. Meanwhile, expectation of the development directions of controlled-release materials is given in order to provide reference for practical application of groundwater remediation engineering. -
