Abstract

Low-grade coffee beans (LCBs), a waste produced in large quantities by the coffee industry, was investigated as a potential low-cost adsorbent for the removal ofmethylene blue (MB) from wastewater. The waste was characterized by SEM analysis and FTIR spectroscopy. Equilibrium and kinetic experiments were performed to study the adsorption process. The equilibrium data were found to be well described by the Langmuir model, from which amaximum adsorption capacity of 476. 2 mg g-1 was derived. A half-adsorption time ranging from 12. 5 to 96. 2 min was estimated by fitting the experimental kinetic data to the pseudo-second-order model. © (2013) Trans Tech Publications, Switzerland.
