A study was begun to determine the fate of limed nitrocellulose NC sludge in a landfill situation and to establish the best method for oxidation of slufides in a nitroglycerin wastewater stream. Prior to the initiation of a lysimeter study on the nitrocellulose sludge, a literature review was conducted to identify potential degradation products and establish a sensitive technique for analyses of nitrocellulose. It was determined that the chemical degradation of nitrocellulose in an alkaline environment was not a simple saponification reaction, but rather involved degradation to a variety of products. The analytical technique developed involved determination of nitrocellulose and other organic nitrate esters. The procedure included separation of the nitrocellulose, quantitative denitration of the organic ester and then analysis of the resulting nitrate using an automated cadmium reduction method. The procedure was tested and found to be repeated to 0.36 mgl or - 0.01 mgl with average recoveries of 90.
