摘　　要：基于Fick扩散定律,建立了载银沸石抗菌剂在蒸馏水、质量分数为65%的乙醇和体积分数为4%的乙酸中的迁移模型。结果表明:该迁移模型不能准确反映蒸馏水中抗菌剂的迁移情况,但其对质量分数为65%的乙醇有较好的模拟效果,同时还能模拟抗菌剂在迁移时间不大于240h时,体积分数为4%的乙酸中的迁移情况。运用所建迁移模型能快速分析出不同初始质量浓度、有效扩散系数、纸张厚度和迁移时间下,载银沸石在抗菌牛皮纸中的迁移情况,为实际生产和生活中抗菌牛皮纸的安全性能评估提供参考。On the basis of the Fick＇s law,the migration model of silver-loaded zeolite antibacterial agent to distilled water,65% ethanol,4%（v/v） acetic acid has been built.Result shows that although the migration of antibacterial agent in distilled water can not be accurately reflected by the model,the migration of silver-loaded zeolite in 65% ethanol and 4%（v/v） acetic acid after 240h can be greatly simulated.Meanwhile,the migrations of silver-loaded zeolite in antibacterial kraft paper under different initial mass concentrations,effective diffusion coefficient,thickness of paper and migration time are discussed by the model in order to provide a new way to the safety assessment of antibacterial kraft paper.
