Biosorption of Chromium (VI) Using Orange Peel

Abstract

In this work sorption potential has been explored by using orange peel form the local market as a bio sorbent by the removal of the heavy metals mainly chromium (VI). Bio-sorbent was prepared following the standard physical and chemical operations. It was planned to find the effect of the contact time, temperature, solution pH, initial metal concentration on the kinetic isotherm. For the stock solution of Cr (VI) ion K2Cr2O7 is used. From the UV-Vis spectrophotometer the absorbance is measured and calibration curve is plotted and using that curve final concentration is determined. The experiment is performed at room temperature. The analysis part shows that the UV-Vis absorbance reading after the sorption is more than the calibration reading.
