Abstract |
A study was conducted which has resulted in the development of tentative sampling and analysis of fluorides emitted from various stationary sources. The study was directed toward developing and understanding the kinds of species which are present in each source emission. The report presents the following information: A review of the various unit processes within the primary aluminum, iron and steel, glass, and phosphate processing industries; industry flow diagrams which include estimates of fluoride throughout; and an inventory of emission species found within each process; Descriptions of sampling apparatus and procedures for gaseous and particulate fluorides, evaluations of the reactivity of sampling train components and sample container materials in the presence of fluoride ion, and a description of recommended apparatus for each industry; Development of analytical methods for measuring fluoride ion; Analysis of field samples collected from each industry to identify the chemical species present and to evaluate the suitability of developed analytical methods for measuring fluoride; and Recommendations for tentative sampling and analysis methods for gaseous and particulate fluoride.
