dc.description.abstractIn present study, pistachio shell was used as an adsorbent to remove Basic blue 41 dye (BB 41) from textile wastewater effluents with a batch and a continuous system. The structure and characteristics of the pistachio shell were determined by pH pzc , FTIR spectroscopy, BET surface area and SEM-EDX analysis. A batch system was used to investigate the effects of dye concentration, pH, quantity and particle size of adsorbent, reaction dura- tion, temperature and ion strength on dye removal performance were investigated. The error analysis methods were employed to get adsorption kinetics and the best -fitting isotherm models for adsorption of BB 41 dye. The results of modeling studies proved that Langmuir isotherms and pseudo -second -order kinetics the best repre- sented adsorption kinetics and isotherm data. Present findings revealed that BB 41 removal was a feasible, spontaneous and endothermic process. Decreasing removal (%) rates were with increasing NaCl and SDS con- centrations. After three cycles, regeneration efficiency was calculated as 65.39%. Continuous mode of operation was used for optimization of process parameters such as initial pollutant concentration, effluent flow rate and bed height. In continuous system, maximum adsorption capacity was identified as 41.77 mg/g. The Adams- Bohart, Thomas and Yoon-Nelson models were used to find of the best fitting model for experimental data of continuous mode of operation. Pistachio shell had yielded quite high adsorption of dye, thus it was also conduced that pistachio shell could effectively and reliably be utilized in treatment of wastewater effluents of textile in- dustry containing Basic blue 41 textile dye.
