摘要
利用自建的液相射流和双脉冲激光诱导击穿光谱技术(LIBS)实验装置,测定了AlCl3水溶液和混合溶液中Al元素的单脉冲和双脉冲激光诱导击穿光谱,给出了单、双脉冲下的最优LIBS实验参数,在最优化实验条件下,得到AlCl3水溶液和混合溶液中Al元素质量分数的单、双脉冲LIBS检测限分别为26.79×10-6、28.85×10-6和11.93×10-6、14.46 ×10-6,双脉冲LIBS检测灵敏度比单脉冲明显提高。
Abstract
By home-made experimental setup with aqueous jets and dual-pulse laser-induced breakdown spectroscopy (LIBS) technique, the dual-pulse and single pulse LIBS are applied to the detection of Al trace element in AlCl3 aqueous and mixed compound solution jets. The optimum parameters of dual-pulse and single pulse LIBS experiment are presented. Both the dual-pulse and single pulse LIBS detection limits of mass fraction of Al element in AlCl3 aqueous and mixed compound solutions are obtained as 26.79×10-6, 28.85×10-6 and 11.93×10-6, 14.46×10-6 respectively under the optimum experiment conditions. It is shown that detection sensitivity of dual-pulse LIBS is enhanced dramatically compared to the single pulse case.
