Chitosan Encapsulation of Ferrate^VI for Controlled Release to Water:Mechanistic Insights and Degradation of Organic Contaminant.

ABSTRACT: Tetraoxy-anion of iron in +6 oxidation state (Fe^VIO₄^2-, Fe^VI), commonly called ferrate, has shown tremendous potential as a green oxidative agent for decontaminating water and air. Encapsulation of solid potassium salt of ferrate (K₂FeO₄) circumvents the inherent drawbacks of the instability of ferrate under humid conditions. In the encapsulated strategy, controlled release without exposing the solid ferrate to the humid environment avoids self-decomposition of the oxidant by water in the air, and the ferrate is mostly used to decontaminate water efficiently. This study demonstrated the formulation of oxidative microcapsules with natural materials present in chitosan, whose release rate of the core material can be controlled
