Slow-release permanganate (MnO4-) gel (SRP-G) is a hyper-saline KMnO 4 solution that can be used for treating large, dilute, or deep plumes of chlorinated solvents in groundwater. Ideally, the SRP-G injected into aquifers will slowly gelate to form MnO4- gel in situ, and the gel will slowly releases MnO4-. Objectives of this study were to develop SRP-G using colloidal silica as gelling solution,...
Permanganate (MnO4-) is a strong oxidant that is widely used for treating chlorinated ethylenes in groundwater. This study aims to develop hyper-saline MnO4- solution (MnO4- gel; PG) that can be injected into aquifers via wells, slowly gelates over time, and slowly release MnO4- to flowing water. In this study, compatibility and miscibility of gels, such as chitosan, aluminosilicate, silicate, and...
