Annotatsiya
Tabiiy tola bo‘lgan ipak fibroin sorbentga immobillangan nitrozin sarig‘i bilan mis (II) ioni o‘zaro kompleks hosil qilishi o‘rganildi. Ushbu ishda mis (II) ionini aniqlashda tanlab ta’sir etuvchan, yuqori samarali bo‘lgan analitik reagent tavsiya etilgan. Dastlab nitrozin sarig‘ini ipak fibroinga immobillash xususiyatlari, so‘ngra metall ioni bilan kompleks hosil qilishining analitik xossalari spektrofotometrik usulda o‘rganilgan. Hosil bolgan kompleks turli spektroskopik va elektrokimyoviy usullar bilan o‘rganildi. Ipak fibroin tolasiga immobillangan nitrozin sarig‘i yordamida mis (II) ionini aniqlash jarayoni o‘zining seliktivligi, quyi aniqlanish qiymatining kichikligi, natijalarning takrorlanuvchanligi, tezkorligi va regeneratsiya qulayligi bilan afzalliklarga ega. Immobillangan nitrozin sarig‘i bilan mis (II) ioni kompleks hosil qilishida reagent va kompleksning spektr signallari mos ravishda 480 va 540 nm hosil bo‘lgan, shuningdek ishlab chiqilgan usulda mis (II) ni quyi aniqlanish chegarasi 0,2 mkg/ml oshmagan holda olingan natijalarda nisbiy standart chetlanish qiymati 0,033 dan kichikligi namoyon bo‘lgan.
