Qutlimuratov nurbek matkarimovichning mahalliy xomashyolar va chiqindilar asosida yangi ionitlar sintezi

Ionitlarning termik barqarorligini aniqlash usuli
Ionitlarning termik barqarorligi Netzsch Simultaneous Analyzer STA 409 PG (Germaniya) uskunasi, termoparoy K-tipa (Low RG Silver) termopara bilan va alyuminili tigeldan foydalanildi. Polimer materiallarning termik barqarorligini o‘zgarishini tadqiq qilish azotli inert muhitda azot ajralib chiqish tezligi 50 ml/min da olib borildi. Temperaturaning o‘zgarish diapazoni 25- 350⁰C da qizdirish tezligi 5 K/min da olib borildi. Tekshirilayotgan moddalar 20-30 mg qiymatda olindi. Jarayonning o‘zgarishi KNO_3, In, Bi, Sn, Zn moddalardan tashkil topgan standart nabordan foydalanildi.
XULOSALAR
1. Mahalliy xomashyo PVX ni gazlarni tozalashda ishlatib bo’lingan chiqindi tarkibidagi DEA va MEA bilan modifikatsiyalash jarayonlariga ta’sir etuvchi omillarni o’rganish natijasida maqbul sharoitlar aniqlandi. Olingan moddalarni identifikatsiyalab hosil bo‘lgan polimer material tarkibida N tutganligi, hamda amino guruhlari hosil qilib PVX zanjiriga birikkanligi fizik-kimyoviy analiz usullari yordamida isbotlandi.
2. PVX asosida olingan sulfokationitni chiqindi tarkibidagi DEA va MEA bilan modifikatsiyalash natijasida yangi poliamfolit olish reaksiyasiga turli xil omillarning ta’sirini o‘rganish natijasida jarayonning maqbul sharoitlari topildi. Olingan moddaning identifikatsiyalab hosil bo‘lgan poliamfolit tarkibida S va N tutganligi, hamda ularning sulfo va amino guruhlari hosil qilib PVX zanjiriga birikkanligi fizik-kimyoviy analiz usullari yordamida isbotlandi.
3. Olingan polimerni IQ-spektroskopik usul bilan identifikatsiyalash orqali tarkibida ikkilamchi hamda uchlamchi amin guruh tutgan anionitlar, hamda poliamfolit tarkibida ham kation almashinuvchi sulfoguruhlar, ham anion almashinuvchi ikkilamchi aminoguruhlari borligi aniqlandi. Olingan ionitlarni skanerlovchi elektron mikrofotografiyalari tahlili uning sorbsiyalash jarayonini osonlashtiruvchi g‘ovak tuzilishga egaligi tasdiqlash imkonini berdi. Shuningdek ionitlarning o‘rganilgan fizik-kimyoviy xossalari sanoat miqyosida suvdagi mavjud ionlarni ajratib olishda ishlatish talablariga mos kelishini ko‘rsatdi.
4. Anionitlarga mis (II), xrom (VI) hamda Mn(VII) ionlarining yutilish kinetikasi tadqiq qilindi, hamda sorbsiya jarayonining aktivlanish energiyasi hisoblab topildi. Olingan natijalar o‘rganilayotgan jarayon psevdo-ikkinchi tartibli reaksiyalar qonuniyatlariga bo’ysinishi sistemadagi ionlar bilan bir qatorda ionit tarkibidagi ionogen guruhlar hisobiga ion-almashinish reaksiyalari borganligidan dalolat beradi. Sorbsiya jarayonining izotermik muvozanatini zamonaviy izoterma modellari yordamida o’rganilganda Lengmyur monomolekulyar nazariyasiga bo’ysinishi aniqlandi. Shuningdek adsorbsiya jarayonida termodinamik parametrlarini o’zgarishi ion-almashinish reaksiya borganligidan dalolat beradi.
5. Mahalliy xomashyolar va chiqindilar asosida olingan granulasimon anionitlar ishtirokida sanoat korxona suvlarini tozalash uchun bir necha marotaba dinamik sharoitda sorbsiya, desorbsiya jarayonlari amalga oshirilganda, uning sorbsion xossalari o‘zgarmasdan qolgani kuzatildi va natijada anionitni sanoat korxonalarida suvlarni tozalashda ko‘p marotaba qo‘llash mumkinligini imkonini berdi. Olingan ionitlar yordamida «MAXAM-Chirchiq» AJ hamda «Muborak gazni qayta ishlash zavodi» AJ texnologik jarayonlarida hosil bo‘ladigan suvlarini oraliq metall ionlaridan tozalashga imkon beruvchi maqbil uskuna ishlab chiqildi va sanoat miqyosida joriy qilinish uchun tavsiya etildi.
