摘要
利用紫外吸收光谱法直接测定COD是一种不用化学试剂、对样品无须加热消解、快速、简洁、无二次污染的绿色技术。本文对此技术的原理、相关概念、特点、进展、技术难点及应用前景作了较全面的评述。
Determination of COD by UV absorption spectrum is a quick and simple analytical technique, which has the advantages of no reagent application, no digestion, and no secondary pollution. As a novel technique for determination of COD, it has been paid more attention. The concept, principle, characteristics, development, technical issue, and its prospect for application are reviewed.
