Correlation of Oxygen Demand and Total Organic Carbon Tests on Wastewaters from Ammunition Plants. Part I. COD and TOC of Pure Explosives.

摘要

New Federal regulations for Effluent Limitations, Guidelines, and Standards for Explosives Manufacturing, Point Source Category, Has led to the evaluation of the specified oxygen demand tests in order to determine their applicability to munition unique wastewaters. In part one of this study, results of chemical oxygen demand (COD) and total organic carbon (TOC) tests performed on solutions of pure energetic materials are reported and discussed. The experimental data was analyzed statistically to determine the correlation between the COD and TOC tests when measuring known solutions of energetic materials; the relationship between actual and theoretical values was also determined. Experimental results show that response to the COD test varies significantly between compounds and is not an accurate indicator of organic loading of munition wastewaters despite its high level of precision. TOC is found to be more accurate and more sensitive. (Author)
