摘要： 用纳米TiO2分别对颗粒状及粉末状竹炭进行改性得到纳米TiO2改性竹炭,并对纳米TiO2改性竹炭(颗粒、粉末)、种炭化温度(500、600、700和800℃)的竹炭及纳米TiO2共7种材料,在无光照条件下对2种霉菌(黑曲霉菌、绿色木霉菌)进行抑菌试验.结果表明:纳米TiO2改性竹炭(颗粒、粉末)抑菌效果最好,其防治效力(E)分别为90%和100%;种炭化温度竹炭的E分别为25%、25%、25%和0,纳米TiO2材料没有抑菌能力,其E为0.试验表明,纳米TiO2改性竹炭比普通竹炭的抑菌效果好,它是一种抑菌能力强的新型竹炭材料.

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
