TI  - Removal of contaminants by activating peroxymonosulfate (PMS) using zero valent 
      iron (ZVI)-based bimetallic particles (ZVI/Cu, ZVI/Co, ZVI/Ni, and ZVI/Ag).

AB  - In this study, four different ZVI/M-PMS systems (e.g., ZVI/Cu, ZVI/Co, ZVI/Ni and 
      ZVI/Ag) were fabricated to investigate the removal of contaminants (Rhodamine B 
      (RB), 2,4-dichlorophenol (2,4-DCP), bisphenol A (BPA), bisphenol F (BPF), 
      levofloxacin (LFX), and chloramphenicol (CAP)). The results indicated that ZVI/Cu 
      and ZVI/Ag exhibited a superior performance to activate PMS compared with the 
      ZVI. The mechanism of the investigation showed that a relatively positive 
      correlation between the release of iron ions (Fe(2+)) and contaminant removal 
      efficiency was found in different ZVI/M-PMS systems. This revealed that galvanic 
      couples affected iron corrosion, and the ZVI/Cu and ZVI/Ag bimetallic systems 
      facilitated the corrosion of ZVI but the ZVI/Co and ZVI/Ni bimetallic systems 
      restrained the corrosion of ZVI. The electron paramagnetic resonance (EPR) 
      analysis and the radical quenching experiments apparently supported the roles of 
      the hydroxyl radical ( OH), sulfate radical (SO(4) (-)) and superoxide radicals 
      (O(2) (-)), which suggest that these reactive radicals were primarily responsible 
      for the degradative route, and the contribution rate may follow the order of 
      SO(4) (-) < O(2) (-) <  OH. Furthermore, investigation of crucial parameters 
      showed that the contaminant removal ratio increased with an increase in the metal 
      ratio (M : ZVI) to a certain limit, and a higher bimetal catalyst dosage and 
      extremely acidic conditions (except for ZVI/Co, which showed the best catalytic 
      performance under neutral condition) enhanced the degradation of contaminants. In 
      the evaluation of real water samples, there was almost no influence from the 
      water matrices compared to the control condition, and the ZVI/Cu and ZVI/Ag 
      bimetallic particles showed great potential to treat various wastewater. 
      Therefore, this study helps to understand the application of oxidation process 
      based on bimetallic particles.
