摘要：Persulfate is one of the strongest oxidants, and offers some advantages over other oxidants because it is a solid at ambient temperature with the ease of storage and transport, high stability, high aqueous solubility and relatively low cost. These features let it to be a promising choice for wastewater treatment and in situ chemical oxidation of organic pollutants in environmental remediation. Reactions of persulfate with organic pollutants, however, are generally slow at ambient temperature, and activation of persulfate is necessary to accelerate the process. Upon activation, persulfate can produce the highly oxidative species, sulfate free radicals, which can react with a variety of organic pollutants. Persulfate can be activated to generate sulfate free radicals by thermal, chemical and photochemical techniques. Many studies have been conducted to investigate efficiencies of activated persulfate for the chemical degradation of environmental pollutants. This paper gives a review on the activation of persulfate and its environmental application, including the following activation methods: heat, UV light, transitional metal, activated carbon, microwave and integrated techniques.
