光度分析由于多元络合物的迅速发展,灵敏度大为提高,选择性虽亦能改善,但相比之下则收效甚微。如何提高其选择性,已成为研究者们的工作目标之一。化学方法应用较普通,但繁复冗长,有时不很有效;也用仪器多元素分析及联用技术如Gc-Ms、Gc-IR等,惜国内尚未普及。借助数学与计算 Photometric analysis due to the rapid development of multi-complex, greatly increased sensitivity, although the selectivity can be improved, but compared with little effect. How to improve its selectivity has become one of the research goals of the researchers. Chemical methods used more common, but complicated and lengthy, sometimes not very effective; also used multi-element instrumental analysis and combined with technologies such as Gc-Ms, Gc-IR, but not yet popular in China.
