Abstract:
Microbial contamination has evolved as a life-threatening problem afflicting people due to various diseases
caused by pathogenic bacteria in drinking water. Thus developing novel antibacterial materials is an urgent
need. Herein, a chitosan (CTS)/ biochar-nanosilver (C-Ag) antibacterial composite was prepared by a method of
CTS-coated on C-Ag obtained through a facile high-temperature carbonization process using corn straw as the
carbon substrate. The results from FT-IR, XRD, SEM and TG-DSC revealed that the biochar loading spherical
silver nanoparticles was coated with CTS in the composite. The antibacterial activity of the CTS/C-Ag composite
was investigated using the plate counting method with Escherichia coli (E. coli), and the results suggest that the
composite exhibited excellent antibacterial activity against E. coli. In this application study, it was proven that
the CTS/C-Ag composite exhibits sustainable antibacterial activity and good reusability for drinking water.
Therefore, the CTS/C-Ag composite has potential application in drinking water treatment.
