Controlled release type potassium ferrate composite as well as preparation method and application thereof

The invention discloses a controlled release type potassium ferrate composite as well as a preparation method and application thereof. The preparation method is as follows: by taking a high polymer which is biodegradable and environment-friendly as a framework material, dissolving the high polymer in a low-boiling point organic solvent, adding a pore-foaming agent, a dispersing agent and high-purity potassium ferrate, adding the mixture into a medium for emulsifying and curing, and filtering and drying the cured product to obtain the controlled release type potassium ferrate composite. The composite is in a water environment, so that a net-shaped duct structure is formed in an inert framework material by virtue of the hydrophilcity of the pore-foaming agent, and therefore, the potassium ferrate is effectively aided to release from the composite, and a problem that dissolution of active ingredients is affected due to texture compaction of the framework material is avoided; the composite is different from the conventional disposable oxidant, controllable in release speed in water, uniform in velocity, long in holding time, good in storage stability, and has wide application prospect on in-situ repairing polluted underground water.
