“…The TOC greatly increased with the arc current decreasing, thereby it is considered that the arc current may have a strong effect on the TOC reduction rate. These results are in good agreement with the work of phenol and alcohol decomposition by the water plasma [12,14] . YUAN et al [13] also observed a higher mineralization extent of phenol solution at a higher input energy.…”

High concentration of aqueous glycerine was decomposed using a direct current (DC) plasma torch at atmospheric pressure. The torch can generate the plasma with water as the plasma-supporting gas in the absence of any additional gas supply system and cooling devices. The results indicated that 5 mol% glycerine was completely decomposed by water plasmas at arc powers of 0.55∼1.05 kW. The major products in the effluent gas were H2 (68.9%∼71.1%), CO2 (18.9%∼23.0%), and CO (0.2%∼0.6%). However, trace levels of formic acid (HCOOH) and formaldehyde (HCHO) were observed in the liquid effluent. The results indicated that the water plasma waste treatment process is capable of being an alternative green technology for organic waste decomposition.

“…Production of H2, C, CH4, H2O, CO, and CO2 were observed from the intensity peaks of 2(H2 , respectively. In the past study about decomposition of 10mol% ethanol solution by water plasma (Nishioka et al, 2009), the intensity peak of 26 (C2H2 + ) was identified. C2H2 was considered to be the intermediate product of the production of soot.…”

During two last decades, numerous technologies and approaches are presented for treating contaminants in liquids and solutions. Among them, thermal plasma has shown rapid kinetic and high destruction efficiencies due to very high temperature and highly active radicals. Hence, the use of thermal plasma for treatment of the contaminants in liquids and solutions has received a lot of attention in view of its low environmental impacts. This review focuses on thermal plasma, and it describes the current status of liquid and solution treatment using this technology. A comprehensive analysis of the available scientific and technical literature on liquid and solution plasma treatment is presented, including the treatment of a variety of contaminants in liquids and solutions via different kinds of thermal plasma. The principles of thermal plasma generation and the available plasma technologies with potential applications to generate valuable products from liquid waste are presented. In addition, the results of the thermal plasma processes for the treatment of specific contaminants are investigated. In light of the investigated literature, thermal plasma is found to have a significant potential to treat the liquid wastes.
