Study on fluoride reduction in artesian well-water from electrodialysis process
چکیده انگلیسی
In this paper two ion-exchange membranes have been examined for ED. The Selemium AMP® anionic membrane (Asahi Glass Co.) and photo-polymeric anionic membrane (MZA™) were tested in an experimental apparatus of a mini-ED cell having two acrylic compartments. The AMP® membrane, with 0.1 A dm−2 current density, removed 69% of the fluoride anion and, with 0.7 A dm−2, removed 97% of the fluoride anion. The MZA™ membrane removed 40% with that current density, without pretreatments. The analytical method for determining the fluoride anion, in every step of the electrodialysis process, was the Ion Analyzer Chromatographic System (DX-80 Dionex with conductivity detector). The results have shows the possibility of using the ED process to remove fluoride from water from artesian wells, thereby improving the quality the potable water in this region.
