摘要:

从有机微量元素的螯合率对于衡量产品的品质、调节工艺条件、研究作用机理3 个方面,阐述了测定螯合率的重要意义;综述了螯合率测定的方法,对凝胶过滤色谱法和有机溶剂萃取法进行比较,指出有机溶剂萃取法测定螯合率可能具有比较好的适用性。

关键词: 有机微量元素, 螯合率, 螯合率的测定, 凝胶过滤色谱法, 有机溶剂萃取法

Abstract:

In this paper, the significance of chelating rate in organic trace element complexes has been demonstrated from three points such as balancing product quality, modulating process conditions and exploring product mechanisms. Determination methods for chelating rate were reviewed here. Based on comparison, organic solvent extraction method exhibited more applicable than gel filtration chromatography.

Key words: organic trace element, chelating rate, chelating rate determination, gel filtration chromatography method, organic solvent extraction method
