用化学定性分析检验聚酯切片中催化剂和添加剂的组分,如Sb~(3+)、Ti~(4+)、Co~(2+)、Mg~(2+)、Zn~(2+)等7种金属离子以及酸根离子(卤素离子、醋酸根离子等)。先把固体试样制备成试液,经初步试验后,再作阳离子的个別检出,使得分离手续和操作方法简便,效率提高。对于阴离子(Cl~-、AC~-)可直接用固体试样检验。本法曾对日本仑富公司的聚酯切片作过分析,所得结果与X-光荧光分析结果基本相符。

The components of the catalyst and additives in the polyester chips were examined by chemical qualitative analysis, such as Sb ~ (3 +), Ti ~ (4 +), Co ~ (2 +), Mg ~ (2 +), Zn ~ (2+ ) And other seven kinds of metal ions and acid ions (halogen ions, acetate ions, etc.). The first solid sample prepared as a test solution, the initial test, and then for the individual detection of cations, making the separation procedures and methods of operation is simple and efficient. For the anion (Cl ~ -, AC ~ -) can be directly used solid sample test. This law had Japan’s rich company’s polyester chips were analyzed, the results obtained and X-ray fluorescence analysis results are basically consistent.
