TỔNG HỢP XANH NANO BẠC (AGNPS) TỪ DỊCH CHIẾT CHỨA ANTHOCYANINS VÀ ỨNG DỤNG TRONG PHÂN TÍCH PB(II), ZN(II)

Tóm tắt

In this study, silver nanoparticles (AgNPs) were bio-synthesized using extract of anthocyanin. The
formation of silver nanoparticles (AgNPs) was confirmed by UV–visible spectroscopic analysis and
recorded the localized surface plasmon resonance (SPR) at 420-446 nm. The hydrodynamic diameter
(98.4 nm) was measured using the dynamic light scattering technique, was performed with a
nanoparticle analyzer. Moreover, these green synthesized AgNPs were found to exhibit good sensing
properties towards Zn2+ and Pb2+ ions in aqueous medium with MDLS = 0.036mM, LOQ = 0.111mM
for Zn2+ and MDLS = 0.041mM, LOQ = 0.136 mM for Pb2+.
