A study on coupling photochemical and biological flow reactors for the degradation of p-nitrotoluene-ortho-sulfonic acid (p-NTS) has been carried out.6
a) p-NTS (presence of nitro and sulphate electron withdrawing groups) is present in effluents from the Swiss chemical industry.
b) The mineralization of p-NTS via photo-Fenton treatment in batch or continuous mode is not a cost-effective strategy.
c) p-NTS is not satisfactorily mineralized by heterogeneous photocatalysis (TiO2/H2O2).7
