摘要
为探讨榕树叶对铀的吸附特性 ,考察 pH、吸附时间、含重金属溶液浓度对吸附能力的影响 ,绘制出吸附等温线 ,并求出Langmuir曲线和Freundlich曲线相应方程 .结果表明 :榕树叶在pH =3 ,吸附时间t=2 0min时吸附铀的能力最高 .重金属离子浓度越高 ,榕树叶的吸附量越高。
The effects of pH, time and biosorption concentration were examined to study the properties of uranium biosorption by Banyan leaves. The isotherms were drawn and Langmuir and Freundlich equations deduced. Results show that highest absorption is achieved when pH value is 3 and time is 20 minute. Quantity of absorption is increased by increased concentration of heavy metal ions.
