Gupta] Summary: A simple field test for the detection of mercury is described. The test is based on the ligand exchange reaction where hexacyanoferrate(III) exchanges its cyanide ions with chromogenic organic ligand succinyl dihydroxamic acid (SDHA). In the reaction the colourless SDHA reacts with yellow K3Fe(CN)6 to give a greenish blue coloured complex in a slightly acidic solution containing mercury. The reaction has been successfully applied for the detection of mercury in polluted water, air and soil samples. In air, at a velocity of ∼0.21/min of the impinging air and a reaction temperature of ∼70°C, mercury(II) as low as 0.01 μg could be easily detected after 3 min exposure. In water the limit of identification and limit of dilution were found to be 0.2 μg Hg(II) and 1:200000, respectively.
