Round robin investigation of organic compounds in aqueous leachates of solid wastes: application to H-coal filter cake leachates

The work presented in this report details efforts of six laboratories to develop methods for the analysis of aqueous leachates from fossil fuel solid wastes and to determine their accuracy and precision. Quantitative data on the concentrations of seventeen target organic compounds in aqueous leachates of a fossil fuel waste are presented. Many of the target analytes were selected from Appendices VII and VIII, of the May 19th, 1980, Federal Register. Some organic compounds that are not present in Appendices VII and VIII were also selected because of the probability of their presence in fossil fuel products, by-products, and wastes. These target analytes and four standard compounds that were used as internal standards are the following: Benz(a)anthracene, o-Cresol, Phenanthrene, Carbazole, Naphthalene, 1,4-Naphthoquinone, Phenol, 2-Fluorophenol (standard), n-Octacosane (standard), Azulene (standard), 2,3,4,5-Tetrachlorobiphenyl (standard), n-Tetradecane, 2-Naphthol, n-Hexanoic acid, Dibenzothiophene, Quinoline, Acenaphthylene, 1-Naphthylamine, 2-Picoline, 4-Aminobiphenyl, and Fluoranthene. An analytical method for the determination of organic compounds in aqueous leachates has been developed. This method was evaluated using a series of samples of increasing complexity, starting with simple synthetic aqueous leachates and ending with leachates of fossil fuel wastes. The present report describes the analytical results from four laboratories applying the previously developed analytical methodmore » to leachates of an H-Coal filter cake material. These leachates were obtained using both the standard ASTM Method D3987 and the EP leaching procedures. Ten additional compounds of interest were identified in the extract: Indan, Tetralin, 2-Methylnaphthalene, 1-Methylnaphthalene, Tetrahydroacenaphthene, Biphenyl, Acenaphthene, Dibenzofuran, Fluorene, and Diphenyl Ether. 11 references, 2 figures, 16 tables.« less
