AB  - Degradation of humic acid (HA), a predominant type of natural organic matter in 
      ground water and surface waters, was conducted using a gas phase surface 
      discharge plasma system. HA standard and two surface waters (Wetland, and Weihe 
      River) were selected as the targets. The experimental results showed that about 
      90.9% of standard HA was smoothly removed within 40 min's discharge plasma 
      treatment at discharge voltage 23.0 kV, and the removal process fitted the 
      first-order kinetic model. Roles of some active species in HA removal were 
      studied by evaluating the effects of solution pH and OH radical scavenger; and 
      the results presented that O3 and OH radical played significant roles in HA 
      removal. Scanning electron microscope (SEM) and FTIR analysis showed that HA 
      surface topography and molecular structure were changed during discharge plasma 
      process. The mineralization of HA was analyzed by UV-Vis spectrum, dissolved 
      organic carbon (DOC), specific UV absorbance (SUVA), UV absorption ratios, and 
      excitation-emission matrix (EEM) fluorescence. The formation of disinfection 
      by-products during HA sample chlorination was also identified, and CHCl3 was 
      detected as the main disinfection by-product, but discharge plasma treatment 
      could suppress its formation to a certain extent. In addition, approximately 
      82.3% and 67.9% of UV254 were removed for the Weihe River water and the Wetland 
      water after 40 min of discharge plasma treatment.
