In this paper, the effects of three coexisting ion systems (Cs, Sr), (Cr, Sr) and (Cs, Cr, Sr) on the adsorption of Sr(II) by irradiated Saccharomyces cerevisiae in solution were investigated. The three systems generally inhibited the adsorption of Sr(II) by yeast. The effects of several environmental factors on yeast adsorption of Sr(II) in coexisting ionic solutions were determined. Three adsorption models, Langmuir, Freundlich and Linear, were used to fit the experimental data. FTIR results showed that the mechanism by which Cs(I) and Cr(III) inhibited the adsorption of Sr(II) was related to the functional groups on the cell wall.

本文研究了三种共存离子体系(Cs, Sr)、(Cr, Sr) 和(Cs, Cr, Sr) 对溶液中辐照酿酒酵母吸附Sr(II) 的影响。这三个系统通常抑制酵母对 Sr(II) 的吸附。确定了几种环境因素对酵母在共存离子溶液中吸附 Sr(II) 的影响。三种吸附模型，Langmuir、Freundlich 和线性，用于拟合实验数据。FTIR结果表明Cs(I)和Cr(III)抑制Sr(II)吸附的机制与细胞壁上的官能团有关。
