随着科学技术的发展,对微量成分的分析提出愈来愈多的要求.近年来,各种期刊关于微量锰的测定,原子荧光光谱法、X—射线荧光光谱法、溶出伏安法、中子活化法、ICP发射光谱法、极谱法等均有不少报导,特别是用原子吸收光谱法测定微量Mn的报导较多.但是,由于分光光度法具有简便、快速、灵敏度高、不需昂贵设备和成本低等特点,不论国内还是国外,都在进行广泛的研究和应用.目前,微量锰的分光光度 With the development of science and technology, more and more requirements are put forward for the analysis of trace elements.In recent years, various journals have been widely used in the determination of trace manganese, atomic fluorescence spectrometry, X-ray fluorescence spectrometry, stripping voltammetry There are many reports about subactivation, ICP emission spectroscopy, polarography and so on, especially the measurement of trace Mn by atomic absorption spectrometry.However, because of its simplicity, rapidness and high sensitivity, spectrophotometry does not require Expensive equipment and low cost, both at home and abroad, are conducting extensive research and application.At present, the trace manganese spectrophotometry
