Summary

On the base of the catalytic effect of Ag+ upon the decomposition of [Fe(CN)6]4−, a very sensitive spot test for the detection of silver has been developed. The sensitivity of the test for the pure system is 0,00075 μg/ drop at the concentration limit 1∶46.400.000. Hg, Au and Pd react analogously. Chlorides and bromides even in high concentrations do not impair the detection of silver. In presence of iodides the sensitivity of the test is slightly reduced.

Zusammenfassung

Es wurde eine sehr empfindliche Tüpfelprobe zum Nachweis von Silber entwickelt. Sie beruht auf der katalytischen Zersetzung des [Fe(CN)6]4−-Komplexes durch Silberionen. In reinen Lösungen können noch 0,00075 μg Silber in einem Tropfen nachgewiesen werden (Grenzkonzentration: 1∶46400000). Hg, Au und Pd reagieren ähnlich wie Ag. Chlorid und Bromid stören auch in großen Mengen nicht. Jodid setzt die Empfindlichkeit des Nachweises etwas herab.
