Abstract
Farg‘ona viloyati Log‘on koni bentonitining boshlang‘ich va natriy karbonat ishtirokida suvli muhitda boyitilgan namunalari rentgenofazaviy tahlil (RFT), infraqizil (IQ) spektroskopiya, elak tahlili, pH-metriya hamda benzol bug‘larining adsorbsiyasi usullari bilan tadqiq etildi. Boshlang‘ich bentonit montmorillonit, kvars, kalsit, illit va dala shpatidan tashkil topganligi aniqlandi. Boyitishdan so‘ng kalsit reflekslarining kvarsga nisbatan intensivligi taxminan 7 marta kamaydi, montmorillonit reflekslarining ulushi esa 1,5 marta ortdi; bu natija IQ-spektrlarda karbonat polosalarining (1417 va 712 sm⁻¹) susayishi va Al–OH polosasining (3625 sm⁻¹) kuchayishi bilan tasdiqlandi. Montmorillonitning d₀₀₁ bazal refleksi boyitilgan namunada 12,4 Å da aniq namoyon bo‘ldi. Quruq elash natijalari boyitilgan bentonitning quritish jarayonida mustahkam agregatlar hosil qilishini ko‘rsatdi (>500 mkm fraksiya 1,4 % dan 31,5 % gacha). Natriylashtirish jarayonida suspenziyaning pH qiymati 8,0 dan 10,0 gacha ortib, yuvishdan so‘ng 7,0–8,0 gacha pasaydi. Bentonitning benzol bug‘lari bo‘yicha sorbsion sig‘imi 15,7 ± 0,6 % ni tashkil etdi.References
