| Abstract: | 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. |
