| Sumari: | Title screen Application of gas-phase pulsed corona discharge (PCD) to oxidation of aqueous pollutants shows unequalled energy efficiency among advanced oxidation processes (AOPs). Improved AOPs often activate extrinsic oxidants. Experimental research was undertaken into sodium persulfate and hydrogen peroxide activation by PCD in oxidation of 1.11 mM oxalate. Oxidant and target compound concentration ratios, pH, gas-liquid contact surface and pulse repetition frequency were studied as control parameters. Results implicated a beneficial effect at oxalate/persulfate molar ratios from 1:0.1 to 1:1 in acidic medium with the optimum at 1:0.5, moderate contact surface and lower frequency. However, the observed synergism of PCD/PS combination decreased with increasing the initial pH of the treated solution. Hydrogen peroxide exhibited negative or neutral impact in all media. Non-assisted PCD proved the most energy efficient approach towards water treatment at neutral and alkaline conditions. Режим доступа: по договору с организацией-держателем ресурса |
