| Abstract: | The method for the determination of phosphorus content in phosphoreted flame retardant is present in this article.Organophosphorous compound is transferred into phosphorated oxide using oxygen flask method under the existion of combustion adjuvant and oxidation accelerator.After the phosphorated oxide is absorbed with dilute sulfuric acid, the ammonium metavanadate and ammonium molybdate are added into the absorption solution to form yellow solution.Finally,phosphorus content of the yellow solution is determinated using spectrophotometry.In this method,the decomposition of sample is rapid and perfect;the colourated solution is stable. The method is convenient with higher precision and accuracy. |
