Based on a chemical pollution site control and restoration project, this paper takes the high salt (SO42 -), acid as the background environment, hydrogen peroxide, Fenton reagent, potassium permanganate, potassium ferrate, sodium persulfate, sodium hypochlorite, activated hydrogen peroxide and sodium persulfate as the oxidants, and seeks to remove the site under the high salt (SO42 -), acid background environment through a series of experiments 2-nitro-4-methoxyaniline (2-N), the characteristic toxic pollutant in groundwater, is the most suitable oxidant. The system is optimized and the kinetic process is discussed, in order to provide theoretical basis and technical support for the remediation of groundwater pollution in the actual site.<br>
