摘要：

Wet oxidation (high-temperature, high-pressure oxidation of organic wastes in aqueous solution) and radiation technology were combined in gamma-ray and electron beam induced oxidation of 4 x 10(-4)-1 x 10(-2) mol dm(-3) Na-phenolate solutions in a wide O-2 concentration (1-20 bar pressure) and absorbed dose (0-50 kGy) range. Most experiments were made in stainless steel high pressure autoclave equipped with magnetic stirrer. The rate of oxidation was followed by chemical oxygen demand and total organic carbon content measurements. The rate was similar in gamma-ray and pulsed electron beam irradiation and increased with O-2 concentration in the liquid. (C) 2011 Elsevier Ltd. All rights reserved.
