Limon Yaprakları Ekstraktından Ag Nanopartiküllerin Biyosentezi ve Karakterizasyonu

Abstract

The synthesis and characterization of Ag nanoparticles from Citrus limonum (lemon leaves) collected the Eastern Black Sea region was investigated in this study. A household microwave system device was used for microwave extraction of lemon leaves samples. The extract was prepared by taking 10g of dried lemon leaves. 10 g of sample was shaken in 100 mL of water for 90 min and extracted in a household microwave device at 4 minutes, 600 W. Ag nanoparticles were synthesized that the obtained aqueous solution was taken in different volumes by mixing 1 mM and 5mM AgNO3 solution. The colloid solution was subjected to microwave in an oven 1, 3, 5, 10, 15, 20 and 30 minutes at 90, 180, 360 W. Then production of AgNPs, the mixture was watched by UV-Vis spectroscopy (Shimadzu UVP-1240 spectrophotometer) measurements at different wavelengths (300 – 800 nm) for SPR of silver nanoparticles. The transition from yellow to a dark brown, shows the synthesis of silver nanoparticles.
