“…The analytical results thus obtained were compared with the existing analytical techniques. For Ag the atomic absorption spectroscopic technique was used for comparison purposes (29). For Ba, Bi, Cd, Cr, Cu, Li, Mg, Mn, Na, Sr, Zn, Ca, B Co, Fe, Ga, Ni, Tl, and Pb the d.c. arc carrier distillation technique (30) was used.…”

“…Although a number of methods are available for the determination of silver ions such as atomic absorption spectroscopy (AAS) 2, 3, inductively coupled plasma‐atomic emission spectroscopy (ICP‐AES) 4, inductively coupled plasma mass spectroscopy (ICP‐MS) 5, all these methods are relatively expensive and require time for sample preparation. Ion‐selective electrodes as alternative analytical methods have been proposed because of their sensitivity, precision, selectivity, simplicity and low cost.…”

An all solid-state Ag(I) ion-selective electrode has been prepared by simply immersing a glassy carbon rod coated with PVCAc, which contained plasticizer and additive but no ionophore, into the AgNO 3 solution. The response of the electrode was linear with a Nernstian slope of 60.25 mV/decade within the concentration range from 1 10 À1 to 1 10 À5 M and with a detection limit of 4.25 10 À6 M. The stability as an effect of various cations was defined. The electrode is suitable for use in high acidic solutions (pH < 1 to 7) and has successfully been applied for the determination of silver(I) concentrations in different samples.

“…16 The fire assay [17][18][19] method is the most commonly used for the determination of silver in ores and ore dressing products. Among the other well known alternatives are atomic absorption spectrometry (AAS) 20,21 and wet chemical analysis 22,23 of the lead assay button in ores and concentrates of these two precious metals. Cathodic and anodic stripping voltammetry 24 based on the introduction of power ultrasound at highly boron doped diamond (BDD) electrode was developed as a sensitive technique for the analysis of trace silver ions.…”
