The purpose of this work is to study the content of nitrate ions in the manifestation of the fire retardant effectiveness of the product of nitric acid processing of low-grade phosphorites for the fire protection of cellulose materials. To achieve the goal of this study, a method was used to study the features of the processes of processing low-grade phosphorites with solutions of nitric acid in various concentrations. To study the effect of concentration (СHNO3 = 5, 10, 20 %) on the solubility of samples (dust fraction (DF)), phosphorite layer-1 (FL1), phosphorite layer -2 (FL2), mineral mass (ММ) low-grade phosphorites and extraction of main flame retardant components Σfire retardant component experimental studies were carried out in the liquid phase. The following methods were used in the research process: chemical elemental analysis, microprobe analysis, infrared spectroscopy, potentiometry, viscometry, special methods for determining the flammability and fire protection of materials.
