“…3 Considering these facts, applying a simple, rapid and accurate method to monitor silver ions at trace levels in various samples is of great importance. Various techniques have been used for the determination of silver in real samples, such as the spectrophotometric method, 4 graphite furnace atomic absorption spectroscopy (GFAAS), 5 high-resolution continuum source ame atomic absorption spectrometry (HR-CS FAAS), 6 inductively coupled plasma optical emission spectrometry (ICP-OES), 7 differential pulse anodic stripping voltammetry (DPASV), 8 and spectrouorimetry. 9,10 Although these techniques are highly sensitive and selective, they require tedious sample preparation and preconcentration procedures, expensive instruments, and professional personnel.…”
