Triclosan (TCS), a kind of widely used pharmaceuticals and personal care products (PPCPs), poses a significant threat to ecoenvironment and human beings. This paper studies the Fenton-like degradation of TCS with the nanoscale zero-valent iron (nZVI). According to the single-factor experiments, the removal efficiency of TCS is increased with the increase of nZVI dosage and H2O2 concentration. And the removal efficiency reaches the highest when the pH value is 3. However, the initial concentration of the TCS had no obvious effect on the removal, and the results demonstrate that the degradation of the TCS follows the second-order kinetics. In addition, the nZVI-based Fenton-like system can achieve the highest removal efficiency under the same experimental conditions, as compared to the traditional Fenton reagent and nZVI alone.
