TAILIEUCHUNG - Efficiency of water hyacinth biomass on removal and recovery of chromium from aqueous solution through column study

The global issue associated with the health of environment and human is the quality of water. A serious threat to the aquatic environment through anthropogenic activities is the heavy metal pollution. Therefore, a suitable cleanup technology should be there for making our environment pollution free. This study reports the sorption behaviour of Cr(III) from aqueous solution by water hyacinth biomass through fixed bed column experiment at bed height of 25 cm, initial Cr (III) concentration of 500 mg L-1 and varying flow rates (, , ml minute-1 ) at optimum pH of . Greater adsorption capacity of mg g -1 was recorded at solute flow rate of ml minute-1 . On increasing the flow rate, the unit adsorption, percent removal, exhaustion and breakthrough time gets declined. Thomas model was found to highly suitable which gave an idea that internal and external diffusion of solute molecules won’t be restricted. The water hyacinth biomass loaded with Cr (III) was desorbed with M HCl at the flow rate of ml minute-1 and regeneration efficiency of the biomass was examined for about three sorption and desorption cycles. The per cent Cr adsorbed and desorbed was found be and % respectively in cycle1 whereas it was declined to and % in cycle 3. Considering the regeneration efficiency was found to be % cycle 2 which was declined to % in cycle 3. Thus, it can be concluded that water hyacinth biomass can be effectively utilized for Cr (III) removal in fixed bed column mode and this technology can be upgraded to larger scale. | Efficiency of water hyacinth biomass on removal and recovery of chromium from aqueous solution through column study
