| Abstract | ||||
| The black tea waste, representing an efficient natural ,bio-adsorbent has been applied for adsorption of some hazardous elements. Several batch wise experiments are conducted to determine the relevant factors affecting its adsorption characteristics especially for uranium. The studied factors are the effects of stirring, agitation time, pH, solid/ liquid ratio and initial metal concentration. The equilibrium data are found to be satisfactorily fitting to Langmuir isotherms. A maximum-metal uptake of 60.56 mg/g was observed for uranium at a solution pH range of 4.5-5.5. The studied elements include U, Th and REEs in the presences of some possible interfering elements. Elution of the studied interesting elements has been achieved and from their eluates proper concentrates have been prepared. | ||||
