Abstract (English):
The modeling binary mixtures of nitric and sulfuric acids at a concentration range from 10-90%, and triplemixtures HNO 3-H 2SO 4-H 2O in range of concentrations: nitric acid10-80%,sulfuric acids10-80%,water 10-80% by ion chromatography has been investigated. Analysis of acidmixtures showed the possibility of using ion chromatography to determine the concentrations sulfuric and nitric acids online in the production of cellulose nitrates. .
