(a) IPM Degradation efficiency by PS alone, Fe(II) alone and Fe(II)/PS, respectively, and (b) the loss of iodine by Fe(II)/PS system under an experimental condition of a initial IPM concentration of 10 μM, a initial pH value of 3.0, at 25 °C, Fe(II) concentration of 0.1 mM and a PS concentration of 1 mM.
