• The removal properties of aqueous phosphate with commercially available boehmite were compared with those with a corresponding compound prepared by the sol–gel method. It was found that the removal rate when using the prepared boehmite was evidently greater than that using the commercial reagent. The removal rate using the prepared boehmite was strongly influenced by the amount of acid added in the peptization step during the sol–gel preparation. As a development of the boehmite utilization, a glass plate was coated with boehmite and utilized for the removal and regeneration of aqueous phosphate. The removal rate of aqueous phosphate was dependent on the dip-coating times and the preparation method of the precursor sol. It was also described that the removed phosphate could be eluted from the coated plate with aqueous ammonium, suggesting that boehmite film can be employed for the continuous removal and regeneration of aqueous phosphate.
