摘要
采用脉冲辐解技术研究了酸性玫瑰红B与水辐射所产生的活性粒子 (·OH、eaq-·、O2 -·)之间的反应及相应产物的瞬态吸收 ;并通过准一级动力学模拟 ,分别测定了酸性玫瑰红B与羟基和水合电子反应速率常数。论述了辐射技术用于处理酸性玫瑰红B废水溶液的反应途径及其机理与动力学。
The reaction of tetraethylrhodamine with the active particals ·OH,e aq -· and O 2 -· generated from the radiation of the aqueous solution are investigated by use of pulse irradiation technique. With plotting apparent first-order kinetic reaction simulated against concentration of it, the reaction rate constants of tetrarthylrhodamine with hydroxyl radical and aqueous electron have been determined. The reaction mechanism of tetraethylrhodamine containing in waster water by radiation technique is discussed.
