Abstract: Nanometer-TiO2 was used to modify granular and powdered bamboo charcoals respectively. These charcoals, together with bamboo charcoals of different carbonization temperatures (500, 600, 700, 800℃), were used in the anti-microbial experiments in the absence of light, and Aspergillus niger and Trichoderma viride were used as representative strains. The results showed that both nanometer-TiO2-modified bamboo charcoals (particles, powders) had the strongest anti-microbial functions, and the prevention efficacies (E) were 90% and 100% respectively. Bamboo charcoal of different carbonization tempertures had poor anti-microbial functions with E of 25%, 25%, 25% and 0 respectively. Nano-TiO2 material did not have anti-microbial functions, and its E was 0. Nanometer-TiO2-modified bamboo charcoal was proved to be a new-style bamboo charcoal material which had strong anti-microbial functions than normal activated carbon.

Key words: nanometer-TiO2, modified bamboo charcoal, bamboo charcoal, anti-microbial functions
