| Abstract | ||||
| Adsorption of uranium using dried roots of water hyacinth plant (E. crassipesas) has been investigated. The plants were collected from Ismailia canal, Sharkia Governorate, Egypt. And pretreated with different activating agents as organic or metallic acids, using fixed concentration from each activator (5%). The adsorption were examined as a function of initial uranium concentration, contact time, pH, temperature, volume, dose of roots and size. Citric acid has advantage and the optimum condition was 94% about pH of 5. | ||||
