Scholarcy highlights

  • The removal of the phenylurea herbicide monolinuron from water was investigated by the electro-Fenton method, based on the electro-catalytic in situ continuous production of large amounts of the strong oxidant hydroxyl radicals
  • MLN decay kinetics was monitored by HPLC, fitting a pseudo first-order reaction, leading to a rate constant kabs = × 109 M−1 s−1
  • A quasi complete mineralization rate of MLN solution was reached after 8 h of treatment on BDD anode with low energy consumption
  • Based on identification of aromatic and aliphatic intermediates, inorganic end-products and TOC removal value, a complete MLN mineralization pathway was proposed
