水體中苯的高級氧化及其反應(yīng)動力學(xué)
摘要： 根據(jù)臭氧的自分解以及臭氧與過氧化氫反應(yīng)誘發(fā)產(chǎn)生OH*自由基機理， 建立了有機污染物降解過程的動力學(xué)模型，并推導(dǎo)出有機物高級氧化過程的速率方程。實驗研究了廢水中的苯在298K和pH=3～9的高級氧化降解過程。在堿性條件下，實驗結(jié)果與導(dǎo)出的動力學(xué)模型相符。 Abstract： A kinetic model has been developed for the degradation of organic pollutants considering both decomposition of ozone molecules and interaction between ozone and hydrogen peroxide for formation of hydroxyl radical and subsequent reactions. Rate equations were derived for depletion of ozone and pollutants in the advanced oxidation processes (known as the peroxone oxidation). Experiments were carried out at 298 K in the pH range of 3 to 9. Kinetic data obtained experimentally from the hydrogen peroxide_ozone reaction and peroxone oxidation of benzene were analyzed by using the proposed rate equations. The experimental results are in agreement with the theoretical model in basic solutions.
