主　　题：Nano-zero-valent iron micro-electrolytic dichloromethanesulfonic acid 

摘      要：Composite carbon-based nano-zero-valent iron materials not only have excellent characteristics of nano materials, but also solve the difficulty of recycling nano materials after use, and overcome the shortcomings of the nano materials. The introduction of copper increases the redox reaction activity of the micro-electrolytic material and expands the applicable pH range of the reaction environment. In the range of pH = 3-9, the removal efficiency of dichloromethanesulfonic acid (Cl-2-MSA) was maintained at 95.5-99.7% after 30 min. Continuous dynamic simulation experiments verified that the composite carbon-based nano zero-valent iron material has a stable removal effect on the target pollutants.
