| Abstract | ||||
| The goal of this research is to study the potential of ZnO nanoparticles as an alternative material for the removal of bisphenol A (BPA) that can be used in ceramic membrane. To safeguard water from organic pollutants like BPA, one of the SDGs' objectives was to ensure access to clean drinking water (goal 6). This research has been studied of various factors for removal of BPA, including contact time, pH, temperature, initial BPA levels, and ZnO NPs dosage. The removal of BPA onto ZnO NPs matched well with the Langmuir, Freundlich, and Temkin isotherm models. The maximum removal efficiency under optimum conditions was achieved 85%. The kinetic data fitted well the pseudo-second order model than other models. The phenomenon for removal of BPA was a spontaneous process and showed the endothermic nature. Thermodynamic, kinetics and isotherm data indicate that more than one mechanism was applied for removal of BPA from water. | ||||
