“…The present of adsorbing material: with the development of industry and society, high concentrations of, and complex wastewater containing fluoride need to be disposed. Hence, biomass, thallus, nano-metal oxide, graphene, metal organic frameworks, carbon nanotubes, polymers, layered double hydroxides, and perovskite are applied to improve the performances of removing fluoride [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. There are also other different adsorbing materials for fluoride removal.…”
