摘    要:对热敏纸中双酚A的溶出、迁移和光降解动力学规律进行了研究,考察了热敏纸中双酚A在人工模拟汗液中的溶出规律,探讨了热敏纸与普通纸在一定湿度和压力下重叠放置时双酚A的迁移转化情况,研究了热敏纸中双酚A在不同温度和时间及不同光源下的降解规律.结果显示,不同光源下双酚A的降解符合一级反应动力学规律;热敏纸中双酚A的总含量约为13.06mg/g,在模拟汗液中的最大溶出量为10.35mg/g,温度和时间是影响溶出量的主要因素;湿度是双酚A从热敏纸迁移至普通纸中的主要影响因素.

关 键 词:热敏纸  双酚A  模拟汗液  迁移  转化  光降解

Abstract:The characteristics of dissolution, migration and photodegradation dynamics of bisphenol A (BPA) in thermal receipt paper (TRP), as well as the dissolving laws of BPA from TRP in artificial simulative sweat were described and explained. The migration and transformation of BPA from TRP to normal paper were investigated as TRP overlapping with normal paper, and the degradation rules of BPA in TRP were researched at different temperature, time and light sources. The results showed the degradation of BPA under different light sources was in accord with the first order reaction kinetics. The content of BPA in TRP was about 13.06 mg/g. Maximum amount of BPA dissolving into simulative sweat was 10.35 mg/g. Temperature and time were key factors which affected dissolution of BPA. Humidity was key factor which affected migration amount of BPA from TRP into normal paper.
Keywords:thermal receipt paper;bisphenol A;simulative sweat;migration  transformation;photodegradation
