Abstract
Abstract A method has been developed for the determination of low concentrations of mercury in air (nanograms/m3), i.e. in the range of the believed natural levels of mercury in the atmosphere (20 ng/m3). Mercury vapour has been collected from up to 2001 of air in glass tubes containing thin films of gold on sieved ceramic powder. In the laboratory theabsorbed mercury was then released into a quartz-window cell by heating the tube in an oven at 500°C. In this paper it is demonstrated that, by using extremely thin films of precipitated gold, quantitative recovery is obtained and memory effects, which result from the use of thicker films, are avoided.
