Abstract

In this study, the utilization of H2SO4 modified oak sawdust (Quercus L.) (HMOS) as a new and promising sorbent for the uptake of an extremely toxic inorganic pollutant, Cr(VI) ions, from aqueous media by batch adsorption method has been investigated. The HMOS has been characterized by different methods such as Boehm titration, pHpzc and moisture content. Some of the process parameters including initial solution pH, equilibrium time, initial Cr(VI) concentration, HMOS amount, and salt effect were examined in detail in order to optimize the experimental conditions for the uptake of Cr(VI) ions onto HMOS. The maximum Cr(VI) uptake was achieved at initial solution pH of 2.5 and at equilibrium time of 240 min. The adsorption behaviors of Cr(VI) ions onto both natural oak sawdust (NOS) and HMOS were analyzed in terms of Langmuir and Freundlich isotherm models and the Cr(VI) adsorption was obtained to be compatible with both isotherm models. The Cr(VI) uptake capacities of NOS and HMOS were calculated as 48.07 and 100.0 mg g-1, respectively by utilizing the Langmuir model. As a result, H2SO4 modified oak sawdust provides a versatile alternative to remove Cr(VI) ions from wastewaters.
