摘　　要：本文对衰减全反射法(ATR)的光学测定原理、衰减全反射-紫外/可见光谱方法(ATR-UV)的特点以及它们在一些典型的工业过程溶液,如高浓度和含有大量固体颗粒和微乳液聚合等体系检测的应用进行了综述。ATR-UV光谱技术适宜实时地反馈工业过程溶液的组分改变和浓度变化,从而帮助我们了解该过程的进展。这些优良的特性能帮助我们开发在线的传感器,因此可用于监测许多典型的工业过程溶液。其方法简单、迅速,一般无需对试样进行预处理或稀释。ATR-UV作为光谱学测定的重要波段,其技术开发将在化工过程检测方面具有重要的意义。This paper describes the principle of attenuated total reflection （ATR） and the features of ATR-UV spectroscopy. It also provides a comprehensive review of the ATR-UV applications in several complicated streams, such as the solutions having very concentrated compositions or significant amount of suspended solids, and the latex of emulsion polymerization. The ATR-UV spectroscopic technique is suitable to be developed as an on-line sensor for monitoring the species of interest in many typical industrial process streams, which provides the real-time information that is very important for the process control. It is very simple and fast, and in general it dose not require sample pretreatment. As an important wavelength range in spectroscopy, the development of ATR-UV technology will be very helpful for not only the process monitoring but also the process study in the chemical engineering related fields.
