谱库最近匹配是聚氯乙烯,但匹配质量非常弱,不足以支持可靠的材料鉴定。观察到的光谱更广泛地描述为一种含氧有机材料,显示脂肪族C-H谱带、一个强羰基谱带和多个O-H特征,与含氯乙烯的谱库条目有一定程度的一致性,但缺乏足够的特征支持以确认PVC本身。
推荐的后续步骤: Re-measure the sample after careful surface cleaning and drying to test whether the O-H bands decrease, which would help distinguish intrinsic hydroxyl functionality from moisture or surface contamination. Inspect the 600-700 cm-1 region at higher quality for characteristic C-Cl-related absorptions expected for vinyl chloride-containing materials. Compare the sample against reference spectra for neat PVC, vinyl acetate/vinyl alcohol-containing copolymers, and common ester plasticizers, especially around 1727 and 1000-1300 cm-1. If available, use complementary methods such as Raman spectroscopy, XRF/EDS for chlorine, or pyrolysis-GC/MS to determine whether a chlorinated vinyl polymer is actually present.
