BIOSORPTION OF HEAVY METAL USING Cr(III) FROM AQUEOUS SOLUTION USING PLANTAIN FLOWER (Musa velutina)

USING PLANTAIN FLOWER (Musa velutina)

The biosorption of Cr (III) from aqueous solution using Musa velutina as a biomass has been studied as a function of IR, pH, contact time, initial concentration, determined using Atomic absorption spectrophotometer. The pH study shows that pH dependence on biosorption and optimum pH is 6. The study on contact time shows that the biosorption is time dependent and maximum biosorption was obtain after 100 minutes. Experimental data were also tested in terms of kinetic characteristics and it found that biosorption process of Cr (III) ions followed well pseudo-second-order. The removal of efficiency increases with increase in concentration, while the adsorption isotherm obtained fitted into Langmuir isotherm than Freudich isotherm. This result indicates that the biosorption process is highly spontaneous and therefore shows that Musa velutina flower could be successfully used for bisorption of Cr (III) from aqueous solution.
