Rapid separation and determination of mercury.
An analytical procedure is described for the separation of mercury(II) by extraction into n-octanol from sulphuric acid solution and then back-extraction as the tetraiodo complex. The mercury is determined by measuring the absorbance of this complex at 322 nm (molar absorptivity 1.95 x 10(3) l.mole(-1).cm(-1)). The procedure is applicable to samples containing copper; the effects of a wide variety of other impurities are tabulated.
