摘要

摘要: 通过静态吸附实验,以酿酒废酵母作为吸附剂,研究了Cu2+、Ni2+及Cu2+和Ni2+共存对酿酒废酵母吸附Pb2+动力学以及等温吸附的影响。结果表明:Ni2+的存在使Pb2+的吸附平衡时间从5min延长到了10min,减缓了Pb2+吸附速率,但对Pb2+的吸附量无影响,Cu2+以及Cu2+和Ni2+共存都使Pb2+的吸附量明显下降,分别下降了35.45%和32.51%。用准二级动力学方程和Langmuir方程对Pb2+吸附过程进行了拟合,发现在本实验条件下可以用准二级动力学方程（R2为0.9953⁰.9999）和Langmuir方程（R2为0.9687⁰.9824）对酿酒废酵母竞争吸附Pb2+的动力学及吸附平衡进行描述。

Abstract: Effects of Cu2 +and Ni2 +on biosorption kinetics and equilibrium of Pb2 +by discarded brewers yeast were studied using static adsorption experiment.The experimental results indicated that the existence of Ni2 +extended the Pb2 +adsorption equilibrium time from 5min to 10 min, slowed the rate of Pb2 +adsorption, but it had almost no effect on Pb2 +adsorption capacity.The existence of Cu2 +reduced Pb2 +adsorption capacity markedly by 35.45%as the existence of Cu2 +and Ni2 +did ( 32.51%) .Competitive adsorption processes were fitted with pseudo-second order kinetics and Langmuir adsorption equation. Pseudo- second order kinetics ( R2 was 0.9953 ~ 0.9999) and Langmuir adsorption equation ( R2 was 0.9687~0.9824) can be used to describe competitive adsorption processes of Pb2 +by discarded brewers yeast under the experimental conditions.
