含镝锌抗菌白炭黑的制备及抗菌性能研究
|
摘要
以工业水玻璃和小苏打为原料,采用溶胶-凝胶法制取载体白炭黑。在一定条件下,将具有抗菌性能的锌元素和稀土镝元素附着在白炭黑载体上,制备得到一种含镝锌型抗菌白炭黑。通过单因素实验分析不同反应条件对产品抗菌性能的影响,确定出较佳制备条件:锌离子浓度为0.7 mol·L-1、稀土镝离子的浓度为0.005 mol·L-1、反应时间为60 min。该制备条件下材料的抗菌率达到80.38%。采用SEM、EDS、BET、ICP和粒径分析等手段对该样品进行表征。结果表明,抗菌白炭黑呈无定形态,且结构松散、粒径小且分布较为均匀,锌含量为3.32%、镝含量为557 mg·kg-1。
The carrier white carbon black was prepared by the sol-gel method and producing from waterglass and baking soda. Zn ion and Dy ion was successfully load on the carrier white carbon black,a kind of white carbon black with antibacterial activity was prepared. Influence of the reaction conditions on the antibacterial materials was studied. The selection range of some fairly optimum parameters and preparation conditions are identified,the concentration of zinc ion is 0. 7 mol·L-1,concentration of rare earth dysprosium ion is 0. 005 mol·L-1 and the reaction time is 60 min. The three factors of controlling the load are better condition,and antibacterial rate is 80. 38%,the samples were characterized by SEM,EDS,BET,ICP and particle size analysis. Returns show antibacterial silica is amorphous,loose in structure,small in particle size and uniform. The zinc content in the material is 3. 32% and the dysprosium content is 557 mg·kg-1.
