Acetic acid is the bulk of an acid mass in so-called produced water which is generated during oil and gas extraction as a by-product. We conducted acetic acid decomposition using our plasma-based advanced oxidation process under several conditions of voltage and solution. The plasma in oxygen bubbles, with an input power of 40 W, achieved a 93% reduction of the total organic carbon (TOC) concentration after 3 h. Experiments under conditions of higher input power, lower pH, or with the use of Ar gas bubbles exhibited slower acetic acid decomposition. We concluded that the efficiency of utilization of the ozone generated by the plasma was greatly affected by the input power and pH of the solution.
