| Abstract |
Elemental mercury, present in the reducing atmosphere of exhaust flue gases from a zinc smelter, may be quantitatively determined by the gold amalgamation technique. The gas sample may be taken using a standard isokinetic stack sampling apparatus in which some of the impingers are replaced by a series of amalgamators, each containing 30 grams of gold chips. Several combinations of impingers and amalgamators were investigated to determine the optimum train configuration. Equations were derived for estimating the collection efficiency of the train from the relative distribution of mercury found on successive amalgamators. Sources of error and possible gold contamination are discussed. Analytical procedures for determining mercury concentration were studied. (Modified author abstract) |
