| Abstract |
The report includes Method 101A (M101A) which is similar to Method 101 for the determination of mercury (Hg) from stationary sources. In M101A, however, acidic potassium permanganate solution is used for sample collection instead of acidic iodine monochloride solution. The method applies to the determination of particulate and gaseous mercury emissions from sewage sludge incinerators and other sources (as specified in the regulations). Particulate and gaseous Hg emissions are withdrawn isokinetically from the source and collected in acidic potassium permanganate solution. The collected Hg (in mercuric form) is reduced to elemental Hg, which is then aerated from the solution into an optical cell and measured by atomic absorption spectrophotometry. After initial dilution, the range of the method is 20 to 800 ng Hg/ml. The upper limit can be extended by further dilution of the sample. The sensitivity of the method depends on the recorder/spectrophotometer combination selected. |
