混合水溶液中多金属元素的激光诱导击穿谱
Laser induced breakdown spectroscopy of multi-metal elements in mixed aqueous solution
摘要
Abstract
Laser-induced breakdown spectroscopy ( LIBS) of trace multi-metal elements in mixed aqueous so-lution were measured by a homemade liquid jet device. The influence of laser pulse energy, ICCD gate delay and width, ICCD gain on signal intensities and signal to noise ratio( SNR) of LIBS were investigated. The experiment parameters were optimized in order to enhance the SNR value. The analysis lines of Cr, Cd, Fe, Ca, Al, Mn, and Pb metal elements were confirmed under the optimum experiment condition. The limits of detection( LOD) of LIBS for these elements were obtained by the measured calibration curves. The measured LOD values range from 0. 018 ppm( Ca) to 41. 231 ppm( Cd).关键词
