Safe disposal of obsolete persistent organic pollutants(POPs)is required by the Stockholm Convention.The incineration of POPs might generate corrosive acid and toxic byproducts.As the alternative,non-combustion technologies like mechanochemical destruction have received attentions from academia and industry.Cogrinding with CaO in high energy ball mill has been proven to be effective for the mechanochemical destruction of chlorinated POPs(e.g.“dirty dozen”).1 However,such process can be time-consuming and sensitive to moisture; also will generate large volume of final residue.In addition,the applicability of CaO for destroying non-chlorinated POPs newly listed into the Convention seems to be questionable,especially for fluorinated POPs.Therefore its necessary to investigate other reagents for better destruction of POPs.In this abstract,some recent studies in our laboratory were presented.
