  • Does activated alumina remove fluoride from water?
  • Ghorai and Pant 19 studied the defluoridation of water samples at an initial fluoride concentration of 12 mg/L using activated alumina and found that the removal efficiency was about 76% at a dosage of 16 g/L and a pH of 7.5.
  • Is alumina a novel adsorbent for fluoride removal?
  • Ekka B, Dhaka RS, Patel RK, Dash P (2017) Fluoride removal in waters using ionic liquid-functionalized alumina as a novel adsorbent. J Clean Prod 151:303–318 Nie Y, Hu C, Kong C (2012) Enhanced fluoride adsorption using Al (III) modified calcium hydroxyapatite. J Hazard Mater 233−234:194–199
  • Does alumina modified expanded medium remove fluoride ions from drinking water?
  • Jin et al ( 2015) studied alumina modified expanded medium for 2 h for the removal of fluoride ions from drinking water. /E-G) at a pH range of 3 –7. The study adsorption was not affected by the pH of the aqueous solution. As such, the ions beyond permissible levels. Abe et al. ( 2004) compared the fluoride
  • How effective is EC treatment for fluoride removal from brackish water?
  • In a study by Missaoui on EC treatment for fluoride removal from brackish water, the removal efficiency up to 52% was achieved under optimal status [ 67 ]. The study by Chibania et al. reported the fluoride removal of over 85% in 20 min using EC technique [ 36 ].
