A new method for the detection of low concentrations of hydroxyl and superoxide radicals, formed by water radiolysis, is described in this article. The method used is the time resolved chemiluminescence. It has been performed with an electron beam delivered by a Febetron 707 accelerator. This method allows to measure hydroxyl and superoxide radical concentrations in a large range of concentrations, between 10(-5) and 10(-8) M.
本文描述了一种检测由水辐解形成的低浓度羟基自由基和超氧阴离子自由基的新方法。所使用的方法是时间分辨化学发光法。该方法是利用Febetron 707加速器产生的电子束进行的。这种方法能够测量浓度范围在10⁻⁵至10⁻⁸ M之间的羟基自由基和超氧阴离子自由基的浓度。
