A novel and efficient diversity-oriented synthetic approach was employed to access the benzo[d]oxazol-5-yl-1H-benzo[d]imidazole on ionic liquid support, which helps to absorb microwave irradiation. In this paper, we successfully coupled 4-hydroxy-3-nitrobenzoic acid onto ionic liquid-immobilized o-phenylenediamine, which subsequently underwent an acid

As promising in-situ chemical oxidation (ISCO) technologies, sulfate radical-based advanced oxidation processes (SR-AOPs) are applied in wastewater treatment and groundwater remediation in recent years. In this contribution, we report for the first time that, thermally activated persulfate oxidation of phenol
