MAQOLA ANNOTATSIYASI

Maqolada terini qayta ishlash korhonasining oqova suvlarini tozalashda ishlatiluvchi yangi adsorbent yaratish masalasi ko'rib chiqilgan. hozirgi vaqtda terini qayta ishlash korhonasi misolida suvni tejab ishlatib, oqova suvni chiqishini va uning ifloslanishini kamaytirish ayni vaqtda O'zbekistonda muhim masalalardan biri ekanligi ta'kidlangan. Umumiy hajmda terini qayta ishlashdagi sarflanadigan suvning foizi hozirgi vaktda amalda nolga teng. Teri ishlab chiqishda turli organik va noorganik moddalarning 150 dan ortiq hillari ishlatiladi. Loyli minerallar va seolitlar uchun ion almashinish bilan bir qatorda fizikaviy va molekulyar sorbciya harakterlidir. Sorbciyalash va gidrofillash birikmalarni tarkibiga kirgan funkcional gruppalarning tuzilishiga bog’liqdir. Loyqa ishqoriy suv o'ziga 84% gacha misning (II) valentli ionlarini yutishi aniqlangan va bentonig loyini modifikaciya qilish imkoniyati natijasida oqova suvlarni tozalanish samaradorligi 83-86 dan 90-95% gacha oshishi tajribada tasdiqlangan. Sorbciyalanishning chiziqli ko'rinishi va turli tuproqlarda adsorbciyalanishlardagi sirt faol moddalarning adsorbcion qavatlari parametrlari keltirilgan. Tabiiy loylarni SVCH-nurlantirish bilan ishlov berishda ularning sorbcion hajmining oshishi qavatlararo bog’lanishlarni hosil qiluvchi akvakompleksning buzilishi bilan qisman bog’liq ekanligi va natijada sorbciyalanayotgan moddaning g’ovaklarga yahshiroq singishiga olib kelishi aniqlangan.
