Abstract

The interaction of silver (I) with allyl- and phenylthioureas (ATU and PhTU) has been studied by means of potentiometric and amperometric titration methods. It has been established that the molar ratio of the reacting components [Ag+ ]:[ATU] ([PhTU])=1:1. The determination of silver may be carried in 0.1–1.0 M solutions of sulfuric acid and 0.1–4.0 М solutions of nitric acid. The combination of the two methods – potentiometric and amperometric titration permits to determine silver (I) in wide range 1.0·10-4–1.6·10-2 M (0.01–0.65 mg/mL) of concentrations. The amperometric titration method has been tested during the analysis of photofilm (determination error equals to 1.45% rel).
