摘要

本文采用激光诱导击穿光谱法(LIBS)测定了苏丹五个不同产地阿拉伯胶(Acacia nilotica)的成分。用80mj脉冲能量的Nd-YAG激光(1064 nm)照射口香糖样品，利用原子光谱数据库对样品发射的等离子体进行光谱分析。结果表明，样品中含有不同量的C、O、H、S、N、P、Na、Mg、Ca、Fe、Cr、Mn、Co等元素。一些元素如(Ti, Br, Ar, Th, Kr, Sc和Pr)是第一次记录在这里。

Determination of Gum Arabic (Acacia nilotica) Constituents Using Laser Induced Breakdown Spectroscopy

In this work, Laser Induced Breakdown Spectroscopy (LIBS) was used to determine the constituent of Gum Arabic (Acacia nilotica) collected from five different locations in Sudan. Gum samples were irradiated with 80 mJ pulse energy of Nd-YAG laser (1064 nm) and Atomic spectra Database was used for the spectral analysis of the plasma emitted from these samples. It was found that the samples contain the elements C, O, H, S, N, P, Na, Mg, Ca, Fe, Cr, Mn, Co with different amounts. Some elements like (Ti, Br, Ar, Th, Kr, Sc and Pr) are recorded here for the first time.
