用~（60）Co γ射线辐照研究了甲基叔丁基醚（MTBE）在氯仿存在下的水溶液破坏。蒸馏水溶液在三个不同浓度的个别溶质MTBE和CHCl 3照射不同的时间，以提供剂量破坏信息。然后，进行MTBE（在两种不同浓度下）和CHCl 3（在一种浓度下）的混合物的照射。一个动力学模型，将最近确定的双分子速率常数来描述的破坏的甲基叔丁基醚和三氯甲烷单独和混合物。这些研究在蒸馏水中进行，大大简化了辐射化学。随着建模能力的提高，我们更接近于能够使用该模型来研究自然沃茨中的“真实世界”混合物。
The destruction of methyl tert-butylether (MTBE) in water in the presence of chloroform has been studied using60Co gamma irradiation. Distilled water solutions at three different concentrations of the individual solutes MTBE and CHCl3were irradiated for various times to provide dose destruction information. Then, the irradiation of a mixture of MTBE (at two different concentrations) and CHCl3(at one concentration) was conducted. A kinetic model was used incorporating recently determined bimolecular rate constants to describe the destruction of the MTBE and CHCl3individually and in mixtures. These studies were conducted in distilled water simplifying the radiation chemistry significantly. With the improvements in the modelling capability, we are closer to being able to use the model to study “real-world” mixtures in natural waters.
