纳米二氧化钛对热带海洋广谱抑菌作用的研究

Research on the Broad-spectrum Bacteriostasis Effect of Nano TiO_2 on Tropical Ocean

[目的]研究纳米二氧化钛对热带海洋细菌的广谱抑菌作用。[方法]在菌液中加入适量纳米TiO2,在UV固化灯照射下,每隔10min采集一次菌液,并进行培养和计数,研究其对热带海洋细菌的广谱抑菌作用。[结果]纳米TiO2在UV固化灯激发下具有很强的抑菌性,且最佳使用量为0.9 g/L。[结论]二氧化钛具有无毒、廉价、光谱抑菌的特点,是一种具有应用前景的新型材料。

[ Objective ] The research aimed to study the broad-spectrum antibacterial effect of Nano TiO2 on the tropical ocean bacterial. [ Meth- ods] nanometer TiO2 was added in suspension under UV curing light, a liquid was collected every 10 min, cultured and counted. [ results] Nano TiO2 has strong antibacterial activity excited by UV curing light , and the best dose is 0.9 g/L. [ Conclusion ] Nano TiO2 is non - toxic, cheapand spectrum antibacterial ,whitch is a promising new material.
