MAQOLA ANNOTATSIYASI

Ushbu maqolada chiqindi maxsulotlardan biosorbentlar ularni hossalari haqida qisqacha ma’lumot keltirilgan. Keltirilgan biosorbentlarga kimyoviy tarkibi o‘xshash va modifikatsiyalashga qulay funksiyanal guruhlarga ega sholi qobig‘ini mochovinaning suvli eritmada modifikatsiya sharoitlari keltirilgan. Mexnik tozalangan sholi qobig‘i, aktiflangan sholi qobig‘i hamda modifikatsiyalangan sholi qobig‘i namunalari tarkibi element analiz tahlili o‘tkazildi. Olingan biosorbentni fizik-kimyoviy xossalari o‘rganildi. Biosorbentni Ni(II) ionini statik sharoitda suniy eritmadan yutish maksimal miqdori 245.8 mg/g ekanligi aniqlandi. Eritma konsentratsiyasi, sorbsiya davomiyligi va haroratning sorbsiya jarayoniga ta’siri o‘rganildi. Biosorbentning metall ionilarini yutgan miqdori, eritmalarning UV-spektrofotometrdagi dastlabki va sorbsiyadan kiyingi nur sindirish ko‘rsatgichlarini eritma kansentratsiyasiga bog‘liqlik grafigi asosida xisoblab topildi. Aniqlangan metall ionlarining sorbent tomonidan yutilish kinetikasini o‘rganib, sorbsiya jarayoni psevdo-birinchi tartibiliy (R2=0.8132) va psevdo-ikkinchi tartibiliy (R2=0.999) kinetik modellari aniqlandi. Bundan sorbsiya jarayoni psevdo-ikkinchi kinetik modelga bo‘ysunishi aniqlandi.
