Research Progress in Application of Slow-Release Materials in In-Situ Remediation of Organic Contaminated Groundwater
In-situ remediation of organic pollution in groundwater often faces challenges such as pollution tailing, rebound, and reverse diffusion. Sustained-release materials (SRM) can slowly release active substances over a long period of time to maintain the long-term effectiveness of in-situ repair, which is a new method to address such issues. Based on relevant research at home and abroad, the composition, preparation methods and reaction kinetics of SRM were introduced. The remediation effects of SRM on organic pollution in groundwater in laboratories and actual sites were also reviewed. Finally, the future development prospects of SRM were discussed.
