摘要:

为研究含锌海藻酸纤维的抗菌性能,首先用不同质量的硫酸锌处理海藻酸钙纤维,通过离子交换制备含不同质量浓度锌离子的海藻酸钙锌纤维。采用3种方法测试了海藻酸锌纤维的抗菌性能。结果显示,由于锌离子从纤维上的释放,海藻酸锌纤维有明显的抑菌圈,并且能阻止细菌的扩散。定量的抗菌试验结果显示:纤维中的锌离子含量越高,其抑菌性越强;锌离子含量为164.4、124.6和84.9 mg/g的海藻酸锌纤维对枯草芽孢杆菌的杀菌率分别为99.77%、28.18%和7.69%;纯海藻酸锌纤维对临床上常见的5种细菌的杀菌率均在98%以上。

Abstract:

In order to study the antimicrobial properties of zinc alginate fibers, this paper used different amounts of zinc sulphate to treat calcium alginate fibers and prepared calcium zinc alginate fibers containing different concentrations of zinc ions through ion exchange. The antimicrobial properties of the zinc alginate fibers were tested using three methods. Results showed that because of the release of zinc ions from the fiber, there were clear zones of inhibition and the zinc alginate fibers were able to block the spreading of bacteria. Quantitative antimicrobial test results showed that the antimicrobial performance was stronger when the zinc ion content in the fiber was higher. Zinc alginate fibers with zinc ion contents of 164.4, 124.6 and 84.9 mg/g showed killing rates of 99.77%, 28.18% and 7.69% respectively against Bacillus subtilisvar. The killing rates against five types of common bacteria for the pure zinc alginate fiber were all above 98%.
