Abstract:
The effect of sawdust to adsorb chromium from aqueous solution was studied .The effects of solution pH, initial concentration, temperature, particle size and sawdust concentration were studied in batch experiments. Experimental studies were carried out to determine the effects of
inlet pH, temperature, metal concentration, particle size, flow rate of solution and column height on chromium sorption in the sawdust fixed-bed columns. As the inlet pH was decreased, the column performance improved. The results show that increasing temperature, sawdust quantity
and decreasing pH value, initial concentration and particle size due to increase in adsorption and increase in break through point. The Langmuir and Freundlich isotherm theories were determined ; the Freundlich model was found to be the best represent the equilibrium isotherm data.
