Solubility of elemental mercury and its role in the cold vapor method
It was demonstrated that the upper limit of assayed mercury contents by the nonflame atomic absorption method (cold vapor method) is determined by the solubility of elemental mercury in water and in other solvents. When the concentration of mercury salts in a solution is above the solubility of elemental mercury, elemental mercury, elemental mercury precipitates during reduction and can not be assayed by the investigated method. The solubility of elemental mercury in water, in 0.1 M CH/sub 3/COOH, in methanol, in ethanol, and in n-butanol was determined. It was established that the solubility of mercury in water depends on the concentration of dissolved oxygen. In practical water solutions, without preliminary removal of gaseous oxygen, the solubility of elemental mercury amounts to 5.85 ..mu..g/ml and this value represents the upper limit for the determination of mercury by the cold vapor method.
