| 摘 要： | 本文用丁二酮肟显色－分光光度法研究了生物材料酵母菌对镍离子的吸附作用，得到了有意义的结果。ｐＨ＝６时吸附量最大，吸附６０分达平衡。盐度及Ｃａ＾３＋、Ｍｇ＾２＋对吸附影响不大。该吸附符合Ｌａｎｇｍｕｉｒ和Ｆｒｅｕｎｄｌｉｃｈ等温吸附方程。

| Abstract: | The beer yeast as the biosorbent of Ni2+ is studied. Nickel cation was determined by dimethylglyoxime spectrophotometry. The adsorbed quantity is larger at pH = 6. The equilibrium time was 60 minutes. Salinity and Ca2+, Mg2+ have no significant effect on the biomaterial uptake. Higher the equilibrium concentration(c) is, larger the adsorbed quantity(q) of yeast is. In addition, relations between c and q were fitted with followed equations: 1/q = 0.340 + 0.0753 x 1/c, r = 0.995; lgq = 3.989 + 0.789 lgc, r = 0.995. So we concluded that the models of adsorption are fitted with Langmuir and Freundlich isotherm adsorption equation. |
