Abstract
In this research, a new low-cost bio sorbent material for application in heavy metal removal focusing on cadmium removal from wastewater. Previous research into tea waste, showed that modification of the surface via bleach and iron (II) chloride has a positive impact on the adsorbent capacity. A full adsorption study was completed by using the optimum MBTW (Magnetic Bleached Tea Waste) from the initial experiment. This experiment differs due to cadmium removal being the focus of the experiment. The Freundlich isotherm was the optimum fit for the experimental data for the three temperatures studied. For the kinetics of the experiment, the most accurate fit was the pseudo second-order kinetics model by Lagergren. Fourier transform infrared (FT-IR) analysis of the MBTW was before and after adsorption which shows the functional groups which changed due to adsorption of cadmium. All the results reported strongly applied the potential of MBTW as an economic bio adsorbent for removal of cadmium from contaminated waters.
