In the present study, Eucalyptus camaldulensis barks/magnetite composite (EBMC) was used for potential application as a low cost adsorbent for the removal of a textile dye Reactive Blue 29 (RB29) from synthetic dye bath wastewater with fixed bed column adsorption systems. The effects of various parameters such as the pH, the column bed depth, and the temperature of the synthetic dye wastewater on the breakthrough time were investigated. It was found that the breakthrough time increased with the increasing pH, the column bed depth, and the temperature. The optimum pH and temperature for the effective removal of RB29 was found to be 9 and 40 degrees C, respectively. The breakthrough time for a 20 cm bed depth was found to be 550 minutes at pH 9 and 40 degrees C. The maximum adsorption capacity was calculated 850.21 mg/g from the Thomas isotherm model under certain operation conditions. The BDST model described (R-2=0.997) the fix bed adsorption process perfectly.
