摘　　要：研究了啤酒酵母对Pb2 + 的吸附行为。酵母菌能有效结合Pb2 + ,pH =6时吸附量最大 ,吸附 6 0分达平衡。盐度及Ca2 + 、Mg2 + 离子对吸附影响不大 ,常温可进行吸附。The beer yeast as the biosorbent of Pb\+\{2+\} is studied. The adsorbed quantity is larger at pH=6. Salinity and Ca\+\{2+\}, Mg\+\{2+\} have not significant effect on the biomaterial uptake. The model of adsorption is fitted with Langmuir Isotherm Adsorption Equation and Freundlich Isotherm Adsorption Equation. Ambient temperature is efficient for lead cation biosorption.
