Open-access A comparative study among methods of sampling mercury so as to evaluate occupational intoxication risk

This is a comparative study of the most feasible methods of sampling mercury vapour. Absorption in acid permanganate, absorption in iodine and iodide solutions, adsorption in activated charcoal, and in hopcalite. A process to produce a standard atmosphere of mercury vapour to test the different methods is described. The method showing greatest accuracy and precision was found to be absorption in acid permanganate.
