摘要

本研究考虑了一种处理塑料废弃物（矿泉水瓶和苏打水塑料瓶的固定环和瓶盖）的新方法，该方法的基础是在硝化气氛中对其进行气相处理，然后处理转化产物。实验证明，将瓶盖样品（低密度聚乙烯、聚丙烯、聚对苯二甲酸乙二酯）置于 12 M HNO3 在 403-423 K 温度下蒸发产生的硝化气氛中 24 小时，然后将转化产物溶解在 1.0 M NaOH 中，并对产生的溶液进行臭氧处理，可以有效处理瓶子废物，而无需考虑塑料的类型。

Processing of Caps and Fixing Rings of Plastic Bottles: A New Approach

A new method for processing plastic waste (fixing rings and caps of mineral and soda water plastic bottles) based on their gas-phase processing in a nitrating atmosphere followed by the disposal of conversion products is considered. It was established that keeping the cap samples (LDPE, PP, PETF) in a nitrating atmosphere obtained as a result of evaporation of 12 M HNO₃ at temperatures of 403–423 K for 24 h followed by dissolution of the conversion products in 1.0 M NaOH and ozonation of the resulting solutions allows efficient disposal of bottle waste regardless of the type of plastic.
