摘要：
This paper studies how chemical modification influences the Saccharomyces Cerevisiae adsorption on copper ion and the desorption of nitric acid, and carries out infrared spectrum analysis of native, adsorbing and desorbing Saccharomyces Cerevisiae. Results show that carboxyl and amino group in Saccharomyces Cerevisiae play an important role in the process of adsorbing Cu( II). The adsorption on Cu( H) by Saccharomyces Cerevisiae is mainly the process of surface adsorption. The process of biosorption on heavy metals is mainly reversible adsorption; however, there still exists irreversible adsorption. FTIR analysis further indicates that carboxyl and hydroxyl adsorption on Cu(11) is reversible adsorption, which amino group adsorption on Cu( II) is irreversible adsorption.
