Antibacterial Zinc Diatomite
Zinc ions were incorporated into the holes of diatomite and the antibacterial effects of the zinc diatomite was evaluated by plate counting of Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). When 1wt% of the antibacterial zinc diatomite was incorporated into paint, almost all the S. aureus and E. coli on the surface were killed. This study revealed that the antibacterial capability of zinc diatomite can kill almost all of the bacteria in the diatomite holes and the surface. The preparation and microstructure of the antibacterial zinc diatomite were also studied.
