Pyrolysis GC Indentification and Determination of Polyester Fibers and Natural Fibers
摘 要
应用裂解气相色谱法测定混纺织物中涤纶纤维与天然纤维的含量。将剪碎成小于2 mm2小块的纤维样品(0.02 g)与固体分散剂石英砂(4 g)混合碾磨成均匀粉末后,称取一定量的样品混合物(其中涤纶纤维含量应小于0.21 mg),置于色谱仪进样口上方的裂解器中,于550 ℃裂解。裂解物经Ultra ALLOY-5色谱柱(30 m×0.25 mm,0.25 μm)分离。根据裂解色谱图所示,不同纤维的特征峰,对样品的纤维进行鉴定。涤纶纤维的线性范围在0.02~0.21 mg之间。采用此法测定了织物样品中涤纶纤维的含量,所得测定值与溶解法测定值相符。用标准加入法做方法的回收试验,测得回收率为94.4%。
Abstract
Pyrolysis-gas chromatography was applied to the determination of polyester fibers and natural fibers. The sample (0.02 g) was sheared into small pieces of sizes less than 2 mm2, and pulverized into a homogeneous powder with quartz stand (4 g) in a quartz mortar. A definite amount of the powdered sample mixture (containing less than 0.21 mg of polyester fibers) was introduced into the pyrolyer and pyrolyzed at 550 ℃. The pyrolyzates were separated on Ultra ALLOY-5 (30 m×0.25 mm, 0.25 μm) chromatographic column and the pyrolytic chromatogram was obtained. Based on the characteristic peaks given by different fabrics, the fibers in sample were identified. Linearity range for polyester fibers was found between 0.02 mg and 0.21 mg. The proposed method was used in the analysis of fabric samples, giving results in consistency with values given by dissolution method. Test for recovery was performed by standard addition method, giving recovery of 94.4%.
