摘　　要：制备了载银沸石抗菌牛皮纸,运用原子吸收光谱研究了40℃下抗菌剂在蒸馏水、4%(体积分数)乙酸、65%乙醇、正己烷和橄榄油中的迁移情况。结果表明:抗菌剂添加量为0.5%的抗菌牛皮纸中含有载银沸石的初始质量浓度为2.85 mg/L。当不同食品模拟物在迁移时间分别为2,24,96,240,960 h时,没添加载银沸石的牛皮纸浸泡的食品模拟液中均未检测到载银沸石,而添加量为0.5%的抗菌牛皮纸在蒸馏水、4%乙酸和65%乙醇中均有迁移,且迁移量大小为:65%乙醇>4%乙酸>蒸馏水,但正己烷和橄榄油中未检测到抗菌剂。The antibacterial kraft paper with silver-loaded zeolite was prepared.The migration of antibacterial agent at 40 ℃ in distilled water,4%（V/V） acetic acid,65% ethanol,Olive oil,and N-hexane were studied by using AAS.Results showed that the initial concentration of silver-loaded zeolite in antibacterial kraft paper with the addition of 0.5% antibacterial agent is 2.85 mg/L;while the time of migration is 2 h,24 h,96 h,240 h,and 960 h respectively,there are no antibacterial agent in kraft paper with 0.0% antibacterial agent;however,migration of antibacterial paper with 0.5% silver-loaded zeolite in distilled water,4% acetic acid,65% ethanol are detected,and the migration amount are 65% ethanol4% acetic aciddistilled water;moreover,antibacterial agent is hardly found in Olive oil and N-hexane.
