Fluoride removal from water by adsorption—A review ...

A high desorption efficiency of 97% was achieved by treating fluoride loaded Fe–Al–Ce oxide with NaOH solution at pH 12.2. The column experiment was also conducted at an initial fluoride concentration of 5.5 mg/L, and pH of 5.8, and 2240 bed volumes were treated with the effluent fluoride under 1.0 mg/L.

8.5.1 Importance of determination. The desorption efficiency of a particular compound can vary from one laboratory to another and also from one batch of charcoal to another. Thus, it is necessary to determine at least once the percentage of the specific compound that is removed in the desorption process, provided the same batch of charcoal is used.
