摘要
文章主要叙述了阻燃剂BDP中磷含量的测定。试样于硝酸和高氯酸中分解后,加入喹钼柠酮沉淀剂形成沉淀,通过过滤干燥,冷却称量后,计算出样品中。
The determination of phosphorus content in flame retardant BDP was present in the article. The BDP samples were decomposed in nitric acid and perehloric acid, and the quimociac was added to form a precipitate. By filtration and evaporation, and cooling and weight, the phosphorus content of the BDP samples were calculated. The method was simple to operate and convenient with higher precision and accuracy and better repeatability. The relative standard deviation was 0.289 %, and the recoveries ranged were 99.25 %-101.25 %.
