Defluorination tace ne ta amfani da aiki alumina adsorbent don defluorination magani. Active aluminum oxide adsorption tacewa ne a halin yanzu fasaha mafi balaga, da ake amfani da mafi m, ingantaccen defluoride hanyar. Active aluminum oxide ne biyu jinsi abubuwa, a cikin ruwa tare da ion musayar, isothermal point a kusan pH = 9.5, lokacin da ruwa da pH darajar kasa da 9.5 za a iya shan anions, lokacin da ruwa da pH darajar sama da 9.5 za a iya shan cations, don haka a cikin acid mafita aiki aluminum oxide ne anion musayar wakili, da fluoride ne mai matukar zaɓi.
