摘要
本文评介了导数测量技术在原子光谱分析中的应用研究进展。介绍了常规原子光谱信号模型及其原子光谱信号的导数模型;讨论了原子发射光谱和原子吸收光谱分析导数测量新技术原理及其分析特性。介绍了导数原子光谱技术在生物样品、环境样品、药物分析、食品饮料、金属及合金样品痕量金属元素分析中的应用。基于信号强度随时间变化的新型导数原子光谱分析新技术较常规原子光谱分析,其灵敏度和基线稳定性显著提高、检出限明显改善,在痕量和超痕量金属元素分析领域有着广阔的应用前景。
Progress in the studies on new derivative atomic spectrometry was reviewed. Models of conventional atomic spectrometric signals and derivative atomic spectrometric signals were described. Basics and characteristics of the derivative atomic spectrometry based on the variety of signal intensity with time were discussed. Applications of the derivative atomic spectrometry to biological, environmental, pharmaceutical and food analysis with higher sensitivity and lower detection limit were described.
