中文摘要
    本文采用波长为532nm的Nd:YAG单脉冲纳秒激光器诱导激发土壤(样品土壤来自蚌埠学院校园),并分析测量了土壤中铜元素的激光诱导击穿光谱特性。以铜元素的特征谱线Cu(393.3 nm)作为分析线,优化了实验参数ICCD门宽,ICCD门延迟对等离子体信号的影响,并在优化后的实验条件下测量分析了土壤中的金属元素种类。实验结果表明优化后的实验参数:ICCD门宽500ns,ICCD门延迟500ns;在该优化条件下检测到样品土壤中含有金属元素:Fe,Cr,Ca,Mg,Cu,Al,Mn。
英文摘要
    A Nd:YAG nanosecond pulsed laser with 532 nm wavelength was adopted to excite and to induce the breakdown of soil of bengbu college campus and the characteristics of laser-induced breakdown spectroscopy(LIBS) of metal element Cu in soil were analyzed. Spectral line intensity and signal-to-noise ratio of the Cu plasma were measured. The effects of ICCD gate width and ICCD gate delay on plasma signal were optimized with wavelength of 393.3nm of Cu as the characteristic spectral line. The types of heavy metal elements in soil were measured under the optimized experimental conditions. The experimental results show the optimized experimental parameters were ICCD gate width 500ns, ICCD gate delay 500ns. Fe, Cr, Ca, Mg, Cu, Al and Mn were detected in the soil samples under the optimized experimental conditions.
