摘要：

The aim of this work was to study the adsorption property of walnut shell (WS) towards dyes. FTIR analysis confirmed several functional groups containing oxygen on WS surface. Methylene blue (MB, cationic dye) adsorption was studied in both batch mode and column mode. The adsorption quantity towards MB was to 80.4 mg/g at 318 K and the process was endothermic. The adsorption kinetics and equilibrium processes were predicted by pseudo-second order kinetic model and Langmuir model, respectively. The shape of the breakthrough curves was affected by dye concentration and flow rate. MB-loaded WS in column was directly applied to efficiently remove Congo red (CR, anionic dye) by secondary adsorption. The column adsorption process was predicted by Yan model. It can be implied that WS have high adsorption potential and it can be used for removal of dye from wastewater. © 2018 Elsevier Ltd
