Mazkur tadqiqotda kremniy dioksid (SiO₂) nanozarrachalari sintez qilinib, ularning nanokompozit teskari osmos membranalarini modifikatsiyalashdagi salohiyati baholandi. Transmissiyali elektron mikroskopiya (TEM) natijalari asosan kvazisferik shakldagi birlamchi nanozarrachalar tarmoqlangan agregatlar hosil qilishini, zarracha o‘lchamlari esa asosan 10–25 nm oralig‘ida ekanligini ko‘rsatdi. Miqdoriy tasvir tahlili namunadagi zarrachalarning qariyb 71 % i 20 nm dan kichik bo‘lib, o‘rtacha diametri 18,4 ± 14,7 nm ekanligini aniqladi. EDS tahlili SiO₂ ning stexiometrik tarkibini va yuqori kimyoviy tozaligini tasdiqladi. Olingan natijalar SiO₂ nanozarrachalarining membrana namlanuvchanligini yaxshilash, filtratsiya unumdorligini oshirish hamda organik ifloslanishga chidamliligini kuchaytirish imkoniyatiga ega ekanligini ko‘rsatdi.
Materiallar va usullarSiO₂ nanozarrachalari nam-kimyoviy sintez usuli bilan olindi va ularning morfologiyasi hamda element tarkibi TEM va EDS usullari yordamida o‘rganildi. Zarracha o‘lchamlari TEM tasvirlari asosida ImageJ–OpenCV dasturiy muhiti yordamida, Gauss filtrlash, Otsu chegaralash va konturlarni aniqlash algoritmlaridan foydalangan holda tahlil qilindi. Ekvivalent diametrlar proyeksiya yuzasi bo‘yicha hisoblandi hamda statistik tahlilda Gauss va log-normal taqsimot modellari qo‘llanildi.
NatijalarTEM tahlili kvazisferik SiO₂ nanozarrachalari tarmoqlangan agregatlar hosil qilishini, asosiy zarracha o‘lchamlari esa 10–25 nm oralig‘ida ekanligini ko‘rsatdi. Miqdoriy tahlil zarrachalarning 71 % ga yaqini 20 nm dan kichik bo‘lib, o‘rtacha diametri 18,4 ± 14,7 nm ekanligini aniqladi. Gauss va log-normal modellashtirish zarracha o‘lchamlari assimetriyasi agregatsiya jarayonlari bilan bog‘liqligini ko‘rsatdi. EDS tahlili stexiometrik SiO₂ tarkibini hamda aniqlanadigan aralashmalarning mavjud emasligini tasdiqladi.
XulosaSintez qilingan SiO₂ nanozarrachalari yuqori kimyoviy tozalik, kichik zarracha o‘lchami va rivojlangan agregat tuzilishi bilan tavsiflanadi. Ular nanokompozit teskari osmos membranalarining gidrofilligini, suv oqimini va ifloslanishga chidamliligini yaxshilash uchun istiqbolli modifikator hisoblanadi hamda suvni samarali tozalash texnologiyalarini rivojlantirishga xizmat qiladi.
