摘要

The Bohart-Adams model has been one of the most widely used breakthrough models for the modeling of dynamic adsorption behaviors of water pollutants in a fixed-bed column. However, the fitting quality was often questioned by many researchers when the Bohart-Adams model was correlated with the experimental data. Recently, Chu (2020) discussed the two simplified forms of the Bohart-Adams model and tested their applicability. In fact, in our previous study (Hu et al., 2019), it has been proved that the two forms represented the logistic and exponential functions in mathematical nature, respectively. The fitting quality depended on whether the experimental data approached the shape of the model curve. Besides, the curve characteristics and fitting ability of the original Bohart-Adams model were not revealed, and how to analyze asymmetrical breakthrough curve remained to be solved. This comment tried to expound the Bohart-Adams model completely. The authors hope that this work will be helpful for readers who are interested in the adsorption studies.
