Biosoroption behavior of yeast to zinc ions in different liquid systems
酵母菌对不同液相体系中锌离子的吸附行为

This paper is mainly to study the biosorption behavior of baker's yeast on zinc ion in two kinds of liquid systems of Zn2+ and Zn2+-Pb2+.Autoclaved baker's yeast was chosen as biosorbent,and then the effect of pH,biomass dosage,the kinetics process and isotherm effect were studied in different systems.At the same heavy metal ions initial concentration,the kincetics showed that baker's yeast is fast and effective biosorbent to Zn2+,and there is always the relation: qt(Pb2+)>qt(Zn2+-Pb2+)>qt(Zn2+).The isother...
