TLDR
Column kinetics for fluoride ion removal could be described more adequately by the Lobenstein model than by conventionally used models as mentioned in this paper, which can be used in a linearized form.Abstract:
Column kinetics for fluoride ion removal could be described more adequately by the Lobenstein model than by conventionally used models. This model can be used in a linearized form. Use of this model minimizes the error resulting from use of conventional models, especially at lower or higher time periods of the breakthrough curve.read more
