Abstract

Quantitative analysis of Sb and Ge contained in PET bottles and their recycled products were performed by microwave assisted acid digestion/ICP-AES. This test method was considered to be useful, because the analytical value of certified materials were corresponded to the certified value. Sb or Ge which used as a polymerization catalyst was remained in PET bottles, and the content of Sb were 128∼198 μg/g (11/21), and the content of Ge were 28∼50 μg/g (10/21), respectively. On the other hand, analytical results of their recycled materials and final products showed that the content of Sb in some cases, for example; a textile goods, a bottle for detergent and a pack of fruits, were high as same as PET bottles. We assumed that new Sb may be added in the new materials blended in the recycling materials.
