In order to solve the groundwater trichloroethylene (TCE) pollution, in this thesis took potassium ferrate (K_2FeO_4) as high effective oxidant, and using encapsulation technology to prepare encapsulation-type K2FeO4, searching its application to groundwater TCE pollution.
First, the high purity K_2FeO_4 was prepared and its determination method was also improved by experiment condition optimization. Research results as follows: taking distilled water, which contains NaOH, and saturated by Cl_2,...
