Abstract

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.
