Abstract
Mazkur tadqiqotda Angren kaolini arzon va mahalliy xomashyo sifatida tanlab olinib, oksalat kislotasi yordamida tozalash va faollashtirish jarayonlari orqali KA (LTA tipidagi) seolit sintez qilindi. Gidrotermal sharoitda olib borilgan sintez natijasida yuqori kristallik darajaga ega KA seolit olingan bo‘lib, uning strukturaviy va adsorbsion xossalari chuqur o‘rganildi. XRD tahlillari seolitning tartibli kristall panjaraga ega ekanligini ko‘rsatdi, FTIR spektral tahlillari esa Si–O–Si va Al–O bog‘larining tebranish zonalarini aniqlab, LTA tipidagi seolitlarga xos ikkilamchi to‘rt a’zoli halqalar (D4R) mavjudligini tasdiqladi. BET va DFT modellari asosida olingan natijalar KA seolitining rivojlangan g‘ovak tuzilma, yuqori sirt maydoni va samarali suv adsorbsiyasi xususiyatlarini ko‘rsatdi. Jumladan, BET yuzasi 8.475 m²/g, DFT yuzasi 19.575 m²/g, maksimal adsorbsiya hajmi 149.00 cc/g, o‘rtacha g‘ovak diametri esa 121.955 Å ni tashkil etdi. Ushbu natijalar KA seolitining yuqori gidrofilligi va samarali adsorbent sifatida qo‘llanish imkoniyatlarini tasdiqlaydi. Tadqiqot Angren kaolinidan seolit sintezida foydalanishning ilmiy asoslarini belgilab, mahalliy resurslardan sanoat miqyosida samarali foydalanish istiqbollarini ochib berdi.
