摘　　要：指出了激光击穿光谱(LIBS)是一种新型的元素分析技术,具有灵敏度高、快速、可多元素同时测量并可在线检测等优点,非常适合针对环境中重金属污染物的实时在线检测.利用自行搭建的一套激光击穿光谱实验装置,开展了对烟气、污水、土壤中重金属的LIBS探测的实验研究,实验结果表明:LIBS技术为解决环境中重金属污染物的实时在线检测提供了技术支持,为将该技术利用到环境保护领域奠定了基础.Laser-Induced Breakdown Spectroscopy （LIBS） is a new technology of elementary analysis, which has features of fast, real-time, online and simultaneous elemental analysis. So LIBS are well suited for online monitoring heavy metal pollution. In this study, a series of new works were introduced. An experimental facility based on LIBS was built and some heavy metal elements were detected in flue gas, industrial wastewater and contaminated soil respectively. These studies provide a great quantity of experimental evidence and technical support for the LIBS to detect heavy metal pollution real- timely.
