polivinilxlorid (PVX), monoetanolamin (MEA), epoksid smola, ion almashinuvchi sorbent, kimyoviy modifikatsiya, IQ-spektroskopiya, termik tahlil, mis (II) ionlari, sorbsion qobiliyat.

Ushbu maqolada polimer chiqindilarini qayta ishlash asosida yangi turdagi ion almashinuvchi sorbentlar sintezi va ularning fizik-kimyoviy xossalari o‘rganildi. Polivinilxlorid (PVX) ikkilamchi xomashyo sifatida qabul qilinib, monoetanolamin (MEA) va epoksid smola yordamida modifikatsiya qilindi. Olingan polimer sorbentning tuzilishi IQ-spektroskopiyasi yordamida tahlil qilindi, termik barqarorligi esa TGA-DTA-DSC usullari orqali baholandi. Mis (II) ionlariga nisbatan sorbsion xususiyatlari sinovdan o‘tkazildi. Natijalar shuni ko‘rsatdiki, modifikatsiyalangan PVX asosidagi sorbent yuqori sorbsion sig‘imga va og‘ir metall ionlarini samarali ushlab qolish qobiliyatiga ega. Mazkur yondashuv ekologik xavfsiz va iqtisodiy jihatdan maqsadga muvofiq sorbentlar ishlab chiqarishda istiqbolli hisoblanadi.
