因此,Fe/Mn@NBC800+PMS系统既涉及自由基方式,也涉及非自由基方式。 作者认为,自由基途径,尤其是SO4•−和•OH,在双酚A氧化分解过程中起着主要作用,因为以BPA为淬灭剂时,双酚A的去除效率最差。 图5不同自由基清除剂对Fe/Mn@NBC800+PMS体系下双酚A降解速率的影响(a)和动力学速率(b);Fe/Mn@NBC800活化PMS...
Hence the strong peaks of ·− SO4 and ·OH were detected in EPR (Fig. 3g). Notably, the NTP removal rate decreased to 17.6% and 14.5% after the addi- tion of FFA and p-BQ, respectively. It was almost com- pletely inhibited in the degradation stage, and the kapp of NTP...
