English Abstract
This research deals with the removal of cadmium from synthetic water using different adsorbents.
The single component adsorption of heavy metal cadmium (II) ions onto powdered activated carbon (PAC), karab, rice husks and corncobs from water aqueous solution was investigated in batch and continuous fixed bed tests.
A multiple correlation was developed to simulate the experimental results.
In batch tests, the effects of pH of solution, adsorbent dosage, contact time, initial concentration, mixing (stirring) speed and particle size diameter were studied.
The optimum values of pH of solution 5.5, for adsorbent dosage 1g adsorbent/100 ml of Cd (II), contact time 30min, initial concentration 125 mg/L and mixing (stirring) speed 100 rpm.
The multiple correlation simulated the experimental data of the batch tests, and regression equations were found for (PAC), karab, rice husks and corncobs with correlation coefficient for each media: 0.984, 0.946, 0.951, 0.932, respectively.
The batch tests were used to determine the equilibrium isotherms data, where the Freundlich model well represented the experimental data.
The rice husk was more efficient than the other three agricultural wastes and PAC for removal of Cd (II).
In continuous fixed bed tests, the effects of flow rate, and bed height of Cd (II) uptake onto rice husks studied.
Different flow rates were used (1,3, 5, 7) L/hr.
Different bed height (10, 20 and 30) cm were used.
The removal of Cd (II) increased as the bed height increased and decreased as the flow increased.
