In order to enhance the adsorption performance of TiO2, CeO2 was tentatively introduced into the matrix of TiO2 by sol-gel method. The prepared adsorbent CeO2-TiO2 was used for the efficient adsorptive removal of antibiotics tetracycline (TC). It was observed that the introduction of CeO2 into TiO2 matrix has improved the removal efficiency of TC by 57.6% compared to pure TiO2. The uptake of TC was highly dependent on the solution pH conditions and the highest uptake of TC occurred under alkaline condition. Linear simulation method failed to discern which kinetic model was better to describe the kinetic data between pseudo-first-order and pseudo-second-order models. By nonlinear simulation, Elovich kinetic model was found to be the best model to describe the TC adsorption onto CeO2-TiO2, indicating that the pronounced diffusion-control process was the rate-determining step. The maximal adsorption capacity of the prepared sorbent was 59.3 mg/g using Langmuir isotherm model at 298 K. The uptake of TC increased with an increase in the reaction temperature, which demonstrates that the adsorption of TC was endothermic.Keywords

Sugarcane bagasse, an agricultural waste biomass was used to prepare biochar by pyrolyzing the biomass under oxygen-limited conditions. The prepared biochar was used for the adsorptive removal of a cationic dye methylene blue (MB) under a magnetic field. It was found that the existence of the external magnetic field had significantly enhanced the uptake of MB onto the bagasse biochar. The increased biochar dosage actually declined the uptake of MB while the effect of the magnetic field was still significant. The adsorption kinetics was investigated under different solution pH conditions. The experimental data were simulated using non-linear pseudo-first-order, pseudo-second-order and Elovich kinetic models. The Elovich kinetic model was found to be more suitable to describe the adsorption kinetics. This indicates that the adsorption of MB onto BC400 is a chemisorption process in which the rate-determining step is diffusion in nature. The uptake of MB is mainly attributed to the π-π electron-donor-acceptor interaction and electrostatic attraction.Keywords
