"MODIFIKATSIYALANGAN ORGANOBENTONITLARNING TEMIR IONLARINI ADSORBSIYALASH QOBILIYATINI BAHOLASH: LENGMUYER MODELI SAMARADORLIGI VA IZOTERMA MODELLARINING TAQQOSIY TAHLILI"
##submission.downloads##
Mazkur tadqiqotda oqova suv tarkibidagi Fe²⁺ ionlarini yangi modifikatsiyalangan adsorbentlar yordamida adsorbsiyalash izotermalari o‘rganildi. Adsorbsion xususiyatlar Freyndlix, Lengmuyer, Dubinin-Radishkovich va Temkin izoterma modellariga asoslangan holda tahlil qilindi. Tadqiqot natijalariga ko‘ra, trimetilammoniy (TMAB) va trietilammoniy (TEAB) bilan modifikatsiyalangan bentoitlar shahar oqova suvlaridagi temir ionlarini samarali adsorbsiyalash xususiyatiga ega ekanligi aniqlandi. Sintez qilingan adsorbentlarning Fe²⁺ ionlarini adsorbsiyalash sig‘imi quyidagicha aniqlangan: PBG bentoiti - 0,151 mg/g; TMAB - 0,164 mg/g; TEAB - 0,168 mg/g. Adsorbsion izotermalar tahliliga ko‘ra, Lengmuyer modeli adsorbsion jarayonlarni eng yaxshi tasvirlab bergan.
