摘  要:
以酞酸丁酯为原料,在无水条件下,采用溶胶-凝胶法合成纳米二氧化钛粉末,通过正交实验法确定制备纳米二氧化钛的最佳工艺条件,并利用XRD衍射仪进行结构表征。采用牛津杯法研究纳米二氧化钛悬浮液对寄生于南丰蜜桔常见菌类的活性抑制效果,并进行实证性保鲜实验,重点考察纳米二氧化钛对贮藏期南丰蜜桔的抑菌性能。所制备的纳米二氧化钛平均粒径为14.6 nm,实际平均产率为90.83%,RSD为0.86%。结论是纳米二氧化钛对贮藏期南丰蜜桔具有一定的抑菌性能。

摘  要:
Nano-scale Titanium dioxide was prepared by butyl phthalate on anhydrous conditions adopting for sol-gel method,and the orthogonal experiment for preparation using XRD diffraction for structural characterization was optimumly investigated..As Oxford cup method was exploited for inspecting Nano-scale Titanium dioxide suspension's repression effect on fungi survived in Nanfeng citrus skin,the empirical fruit fresh experiment was carried out.Nano-scale Titanium dioxide's antibiotic activity on Nanfeng citrus was emphatically investigated.The average diameter of Nano-scale Titanium dioxide powder attained to 14.6nm,but the actual average yield was 90.83% with RSD(Relative Standard Deviation) of 0.86%.The conclusion was Nano-scale titanium dioxide had good antibacterial property on Nanfeng Citrus in storage periods.
