分光光度法作为一种微量组份的检测手段,在分析化学领域中一直起着重要的作用。但是,高选择性的原子吸收光谱分析的发展,使分光光度法正面临着一场挑战。不过,由于分光光度计较为价廉,操作较为简便,并且还由于有大量成熟的分析方案,使分光光度法在科研和生产上依然有着广阔的应用前景。虽然如此,向高灵敏度,高选择性及高速度方向发展仍然是该法今后的主要任务,其中尤以提高选择性更为重要。 Spectrophotometry, as a measure of trace components, has always played an important role in analytical chemistry. However, the development of highly selective AAS spectroscopy is facing the challenge of spectrophotometry. However, due to the low cost of the spectrophotometer, the operation is simple, and because of a large number of mature analytical programs, spectrophotometry still has broad application prospects in the research and production. Nevertheless, the development toward a high sensitivity, high selectivity and high speed remains the major task of the law for the future. Especially the enhancement of selectivity is even more important.
