水、土壤和脐橙中铬的激光诱导击穿光谱研究
Investigation of Chromium in Water, Soil and Navel Orange by Laser-induced Breakdown Spectroscopy
摘要
Abstract
To study the characteristics of Cr spectrum by laser-induced breakdown spectroscopy (LIBS) in navel orange,water,and soil in the growing environment of Gannan navel orange.The Cr spectrum was used to analyze the three samples qualitatively and Cr Ⅰ 425.435 nm was the analysis object.The relative standard deviation (RSD) and signal-to-noise ratios of the three samples were analyzed.The RSD of solution,soil and navel orange were 8.7％,7.1％ and 11.7％ and the signal-to-noise ratios were 3.28,10.27 and 5.34,respectively.the sample shape and surface roughness caused the difference of Cr spectrum by LIBS in the three samples.So if we want to get the high-quality laser induced breakdown spectrum,we should not ignore the effect of the surface of samples on laser induced breakdown spectroscopy.关键词
