摘要: 近年来,对氨基酸离子交换平衡虽有不少研究[1~4],但涉及超当量吸附的研究并不多见,且解释亦各有不同[6~7].本文拟对超当量吸附机理作深入研究.

关键词: 氨基酸, 离子交换树脂, 超当量吸附

Abstract: The adsorption isotherms of glycine, the infrared spectroscopy of glycine adsorbed on the ion exchange resin and the desorption rate of glycine from the ion exchange resin were used to study the mechanism of superequivalent adsorption of amino acid on the ion exchange resin.It can be concluded that the mechanism of the superequivalent adsorption is the formation of the second layer of glycine molecule, and the carboxylic groups of the first layer of glycine on the ion exchange resin act as the exchange sites for the second layer of glycine.

Key words: Amino acid, Ion exchange resin, Superequivalent adsorption
