Özet

Bu çalışma; asit hidrolizi yöntemi ile atık kâğıtlardan selüloz nanokristallerinin (CNC) üretimi, üretilen CNC ve AgNO3 çözeltisinin karıştırılması ve ortama NaBH4 ilavesi ile Ag+ iyonlarının Ag0’a indirgenmesi sonucu CNC/AgNPs nanokompozit malzemenin sentezlenmesi, CNC/AgNPs malzemesinin UV-vis spektroskopisi, DLS, SEM, EDX ve XRD yöntemleri ile karakterizasyonu ve H2O2’nin kolorimetrik tespitinde sensör olarak kullanılabilirliği çalışmalarının sonuçlarını içermektedir. CNC/AgNPs nanokompoziti ile H2O2’nin nicel analizi için 0,001-1,0 mM H2O2 derişimi aralığında bir kalibrasyon doğrusu oluşturulmuş, CNC/AgNPs’nin H2O2’yi minimum tespit sınırı 0,7864 μM olarak belirlenmiştir. CNC/AgNPs’nin H2O2’ye seçiciliğinin belirlenmesi amacıyla çeşitli bileşenlerin varlığında CNC/AgNPs ile H2O2’nin kolorimetrik tespiti çalışmaları gerçekleştirilmiş; KCl, Al(NO3)3, oksalik asit, laktik asit, glikoz, laktoz, maltoz, fruktoz, sakkaroz, üre bileşenlerinin varlığında CNC/AgNPs’nin H2O2’nin kolorimetrik tespitinde etkin bir şekilde kullanılabileceği sonucuna varılmıştır.
