Abstract

A plasma generated at the water boundary can be a useful tool for water purification or hydrophilization of multilayer graphene powder. A combined ozone/plasma system was proposed for mineralizing a high density persistent substances in water. A multiple pin-hole plasmas increased the hydrogen-peroxide supply rapidly for advanced oxidation processes. The mineralization speed was increased to 0.4 gTOC/L/h at the energy efficiency of 0.5 gTOC/kWh. Hydrophilization of multilayer graphene powder suspended in water was conducted using Ar plasma generated above the solution. Hydroxyl group were modified to the multilayer graphene and the dispersibility was improved with very short treatment time of several minutes.
