基于紫外光谱分析的水质监测技术具有实时在线、 无试剂、 无需样品预处理、 无二次污染、 体积小、 成本低等特点, 在对饮用水、 地表水、 工业废水等水体的在线监测中具有显著优势, 已成为现代水质监测技术的一个重要发展方向。 本文介绍了基于紫外光谱分析的现代水质监测技术的原理、 特点、 现状及发展的新趋势, 并提出亟待解决的关键技术问题。

The water quality monitoring technology based on ultraviolet spectrum analysis has the characteristics of small volume, low cost, and no secondary pollution, and it doesn’t need any reagent and sample pretreatment. On account of these characteristics, the direct ultra-violet technology has remarkable superiority over traditional technologies when applied in online monitoring of drinking water, surface water and industrial wastewater, and it has become an important development tendency of modern water monitoring technologies. The principle, characteristics, present situation and development trend of modern water quality monitoring technology based on ultra-violet spectrum analysis were introduced, and the key technical problems were further discussed in this paper.
