Adsorptive removal of Bisphenol A from aqueous solutions by Pistacia atlantica: isotherm and kinetic Studies

Abstract The aim of this study is to investigate the possibility of Pistacia atlantica Biomass as an alternative adsorbent for Bisphenol A (BPA) removal from aqueous solution. The effect of various parameters including contact time, solution pH, adsorbent dosage and Bisphenol A concentration was investigated in this experimental-lab study, Also, the isotherm and kinetic studies was performed for phenol adsorption process. The adsorption equilibriums were analyzed by Langmuir, Temkin, Freundlich and Harkins Jura isotherm models. It was found that he data fitted to Langmuir (R2=98) better than other isotherm models. Batch kinetic experiments showed that the adsorption followed Pseudo second -order kinetic model with correlation coefficients greater than 0.99. According to achieved results, it was defined that P. atlantica not only was an inexpensive absorbent, but also a quite effective factor in removal of BAP water and wastewater.
