Trace element determination in environmental pollution: A kinetic method for mercury estimation.
A method is developed for the estimation of mercury in trace concentrations by measuring spectrophotometrically its catalytic effect on the rate of substitution of p-nitrosodiphenylamine into hexacyanoferrate(II). Under the specified conditions the detection limit is found to be 2.0 x 10(-8)M relative standard deviation 1.4%. The effect of other ions is discussed.
