turning heterocyclic pollutants into polymers from industrial wastewater is a promising method which opens a new door for feasible, cost effective aromatic wastewater treatment. CuO displayed high reactivity for the catalytic oxidation of thiophene by persulfate (PS) in pH-neutral conditions; the observed rate constant (kobs) for the PS-CuO system was â?0 times that of the PS-alone system at pH 7.0. the linear relationship between consumed PS and removed thiophene showed a complete removal of 1.0 mM thiophene from solution required 1.11 mM PS in the PS-CuO system, indicating thiophene has not been completely mineralized to CO2 and water. quenching experiments and EPR anal. ruled out contributions of O2â?sup>- and 1O2 to thiophene oxidation, suggesting that although SO4â?sup>- and OH– contribute to thiophene oxidation to some extent, they are not the primary oxidants in the PS-CuO system at pH 7.0. the presence of thiophene radical cation indicated electron abstraction from thiophene is an important oxidation pathway. produced thiophene radical cations are polymerized into polymers. solid characterizations further confirmed polythiophene-S,S-dioxide is the primary oxidation product. an electrochem. anal. indicated produced polythiophene-S,S-dioxide polymers showed pseudo-capacitive characteristics and can be used for capacitors.
