Bu çalışmada, Doğu Karadeniz Bölgesinde toplanan limon
yapraklarından (Citrus limonum)
Ag nanopartiküllerin sentezi ve karakterizasyonu araştırılmıştır. Limon
yaprağı örneklerinin mikrodalga ekstraksiyonu için bir ev mikrodalga sistemi
cihazı kullanıldı.10 g kurutulmuş limon yaprağı alınarak ekstrakt hazırlandı.
Oda sıcaklığında, 10 g numune 100 mL suda 90 dakika çalkalandı ve bir ev
mikrodalga cihazında, 600 W gücünde 4 dakika ekstrakte edildi, elde edilen sulu
çözeltiden farklı hacimler alınarak 100 mL AgN03(1,
5 mM) çözeltisi ile karıştırılır ve karışım, 90, 180, 360 W gücünde 1, 3, 5,
10, 15, 20 ve 30 dakika boyunca mikrodalgaya maruz bırakılarak Ag
nanopartikülleri sentezlendi. Daha sonra üretilen AgNP'lerin kolloid çözeltisi,
AgNP'lerin yüzey plazmon rezonansı (SPR) için UV-Vis spektroskopisi ile
(Shimadzu UVP-1240 spektrofotometre) farklı dalga boylarında (300 - 800 nm)
ölçümleriyle izlendi. Sarıdan koyu kahverengiye renk değişimi gümüş
nanopartiküllerin sentezini gösterir.

(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.
