摘要
设计并建立了一套用于土壤中重金属污染元素检测的激光诱导击穿光谱(LIBS)检测系统。利用该系统对含多种重金属元素的样品以及土壤样品进行了实验与分析,检测出了Cd,Cu,Pb,Cr,Zn,Ni等重金属元素的主要分析谱线。对配制的含微量Cu、Cr元素的土壤样品进行了实验分析,检测结果达到国家土壤环境质量标准规定的三级土壤中Cu、Cr的含量要求,表明该系统可以进行土壤重金属污染的快速检测。
A Laser induced breakdown spectroscopy（LIBS） system used for detecting heavy metals in polluted soil was established.Samples containing various heavy metals such as Cd,Cu,Pb,Cr,Zn,Ni and soil sample were analyzed by this system,and main spectral lines of heavy metals and main elements were recognized.Soil sample containing trace element Cu,Cr were then analyzed,which are below the trace element thresholds for Class 3 soil used in the Environmental quality standard for soil in China.So the feasibility of UBS system for instant detection of heavy metals in polluted soil was verified.
