چکیده
The paper studies the synthesis, performance, and modeling of conducting copolymers poly (o-phenetidine- co-o-anisidine/TiO2), poly (o-phenetidine-co-o-toluidine/TiO2), poly (o-phenetidine-co-o-toluidine/Fe3O4) and poly (o-phenetidine-co-o-anisidine/Fe3O4) on the stainless steel electrode in a batch reactor for removal of fluoride ions. Electrically switching ion exchange as a safety method was used as the ion exchange process. In addition, modeling and optimizing of the process was done by a response surface methodology (RSM) based on central composite design (CCD). The independent variables in the RSM include applied potential (V) and pH of fluoride solution. A real tap water was chosen as the water sample. poly (o-phenetidine-co-o-anisidine/Fe3O4) has shown better results in the fluoride ions removal and regeneration-reuse process. poly (o-phenetidine-co-o-anisidine/Fe3O4) under controlled conditions of pH: 6.26 and applied potential: 1.06V, shows a high ability in fluoride removal of 71.76% and after three successive cycles still has an ability of 16%.
