DENITRATION OF WASTEWATER GENERATED BY NITROSATION OF ORGANIC COMPOUNDS
Subject of the article was to study the method aimed at denitration of liquid wastes that appear during the nitrosation of organic compounds. Liquid waste represents an aqueous solution of sodium sulfate with sodium nitrate and nitrite as admixtures. The method involves addition of sulfuric acid to...

Liquid waste represents an aqueous solution of sodium sulfate with sodium nitrate and nitrite as admixtures. The method involves addition of sulfuric acid to the wastes followed by drying and thermal treatment of a salt mixture at temperature above 150 °C. Experimental study revealed that sodium nitrite fully decomposes in the solution during the drying resulting in formation of sodium sulfate, nitrogen oxide, and nitrogen dioxide. Solid-phase interaction of sodium hydrogen sulfate and sodium nitrate was investigated by combined DSC-TG technique in the temperature range 100 - 270 °C. The mixture of salts was obtained by drying the aqueous solution. It was shown that the reaction rate is defined by the removal rate of vapors formed nitric acid.http://pubs.ub.ro/?pg=revues&rev=cscc6&num=201704&vol=4&aid=4636sodium sulfatesodium nitratesodium hydrogen sulfaterecyclingthermal analysispolymorphic transitions |
