MARGANES (II) IONINI IMMOBILLANGAN H-RESORSINOL REAGENTI BILAN SORBSION- SPEKTROFOTOMETRIK ANIQLASH
##submission.downloads##
Mazkur ishda marganes (II) ionini H-resorsinol azoreagenti asosida sorbsion-spektrofotometrik aniqlash usuli ishlab chiqildi.
Organik reagent ipak fibroin tolali sorbentiga immobilizatsiyalandi va kompleks hosil bo‘lishining optimal sharoitlari (pH, reagent
konsentratsiyasi, vaqt) aniqlandi. Mn(II) ioni bilan hosil bo‘lgan kompleksning maksimal nur yutilishi 510 nm da kuzatildi, molyar
so‘ndirish koeffitsienti ε=18223 ga tengligi hisoblandi. Usul yuqori kontrastlik (Δλ=40 nm) va yaxshi sezgirlikka ega ekanligi
isbotlandi. Kubelka–Munk funksiyasi asosida nur qaytarish tahlili bajarildi. Taklif etilgan usul ekologik obyektlar va oqava
suvlardagi kam miqdordagi marganes ionlarini aniqlashda samarali va amaliy jihatdan qulay hisoblanadi.
