further enhance the bacterial removal capability, we synthesize a
biotemplated hierarchical porous material coupling chemical components
and hierarchical microstructure, which is derived from rice husk.
The results show that the chemical components and hierarchical microstructure
of the prepared material could both be factors in enhancing the bacterial
removal capability. On the basis of the experimental results, we propose
a hypothetical enhanced bacterial removal mechanism model of the prepared
material. Furthermore, we propose a hypothetical method of inferring
bacterial physical removal effects of samples by their dye adsorption
results. Also, the hypothetical method has been proven to be reasonable
by the experimental results. This work provides a new paradigm for
bacterial removal and can contribute to the development of new functional
materials for enhanced bacterial removal in the future.
