摘要
研究了高铁酸钾处理环境水中溶解性有机物的三维荧光光谱。研究结果揭示了用高铁酸钾处理有机质过程中几种主要溶解性有机质的荧光变化规律,及其影响因素。环境水的p H值对有机质的荧光强度和位置有较大影响。在溶解性有机物降解去除过程中,存在快速衰减和慢速衰减两个过程。三维荧光光谱法可作为一种简单、快速的方法用于环境水中不同类型荧光物质变化的实时监测。
The three-dimension exaction and emission matrix fluorescence spectroscopy（ 3D EEM） was used to investigate the decomposition of DOM in environmental water treated by potassium ferrate. The results showed the changed regular of fluorescence of several organic maters during the treatment process,and the p H value performed an important role on the fluorescent intensity and position. The intensity of fluorescence experienced a quick-decay process and a slow-decay process. Such 3D EEM method can be used as a simple and quick method for the online monitor of variety fluoresce maters.
