中文摘要:
      以3种纸杯样品为研究对象,使用微量点滴样法研究了有机模拟污染物邻苯二甲酸二丁酯(DBP)、二苯甲酮在纸杯样品和空气间的分配系数(K-paper/air)。研究发现,分配系数值随着温度的升高而减小。70 ℃时,DBP、二苯甲酮的K-paper/air值范围分别为105.723~1638.894和67.469~991.849;而100 ℃时K-paper/air值范围分别为28.661~360.978和7.506~407.225。K-paper/air值不仅与污染物的沸点有关,还与纸杯样品的厚度、定量及紧度有很大的关系,厚度、定量、紧度越大,分配系数越大,纸杯样品中的DBP越不易发生迁移。
英文摘要:
      The partition coefficients K-paper/air of DBP and benzophenone between three kinds of paper cups and air were studied using microsamping. The results showed that K-paper/air decreases with temperature increasing. At 70 ℃, the range of K-paper/air of DBP and benzophenone is 105.723~1638.894 and 67.469~991.849 respectively; while at 100 ℃, the range is 28.661~360.978 and 7.506~407.225. K-paper/air value is not only related to the boiling point of the compound, but also to the thickness, ration and tightness of paper cup. K-paper/air increases with thickness, ration and tightness increasing, and this leads to lower migration of DBP in paper cups.
