石墨富集方式下水中 Cr元素的 LIBS检测
Chromium detection in water enriched with graphite based on laser-induced breakdown spectroscopy
摘要
Abstract
In order to study the spectroscopy emission characteristics of chromium in water enriched with graphite based on laser induced breakdown spectroscopy , the characteristic spectral line of 425.435nm was selected for chromium in the experiment when a Nd∶YAG laser in 1064nm wavelength was used as an excitation source , the echelle spectrometer and intensified charge coupled device detector with high resolution and wide spectral range were used for spectral separation and high sensitive detection .The results show that detection optimal delay time is 1100ns and gate width time is 1800ns.The calibration curve of chromium was plotted based on different concentration measurement results , and the limit of detection was 0.520mg/L.The results of the experiment provide the data reference for fast measurement of chromium in water based on laser-induced breakdown spectroscopy .关键词
