Sažetak

A sensitive and selective test for the detection of mercury has been developed based on the strong catalytic action of mercuric ions on the decomposition of hexacyanoferrate (II) in the presence of nitrosobenzene. The sensitivity for the pure system expressed as limit of identification (in 0.05 ml.) is 0.002 microgram of mercury at a limiting concentration o f 1 to 25,000.000. Of the cations studied only silver and gold give an analogous reaction. By following an appropriate procedure, mercury can be detected even when it is present in mixtures with cations giving coloured precipitates with the hexacyanoferrnte (II).
