| description | In this work, the sorption capacity of a bone-based activated carbon for the Black Krom KJR dye removal was investigated in a batch system. Preliminary sorption tests were performed in order to assess the effects of initial pH, sorption temperature, stirring speed and the particle size on the sorption process. The most reliable conditions were used to perform the kinetic and equilibrium tests in duplicate. From the kinetic sorption experiments, an equilibrium time of 24 h was achieved with a sorption capacity of 53 mg·g-1. Kinetic dye sorption data was well represented by both the pseudo second order and Elovich models. Among used isotherm models, the Langmuir model exhibited best fit to the equilibrium sorption data, showing a maximum sorption capacity value of 154 ± 8 mg·g-1 and affinity constant value of 0.0114 ± 0.0012 g·L-1, respectively. Based on these results, it is remarkable the great potential exhibited by the bone-based activated carbon adsorbent for its application in industrial wastewater treatment systems. |
