Description:
An analytical procedure for determining the mercury emissions from mercury cell-chlor-alkali plants is described. This procedure was developed to correct problems in an analytical procedure promulgated by the Environmental Protection Agency. This improved analytical procedure was subjected to a collaborative test in which 13 laboratories performed duplicate analyses on 3 solutions that contained mercury concentrations in the range of 2 to 65 micrograms of mercury per milliliter. From this collaborative test the following estimates are made about the precision and accuracy of the improved procedure: the within-laboratory standard deviation is 1.6 micrograms Hg/ml, the between-laboratory standard deviation is 1.8 micrograms Hg/ml, and the accuracy is -0.4 micrograms Hg/ml.
