摘要
采用过硫酸钾-硝酸消解法对二磷酸哌嗪中的磷进行消解,消解后溶液采用喹钼柠酮沉淀剂进行沉淀,对沉淀进行干燥称量,计算其中的磷含量.此方法准确度高,重现性好,是常量磷含量测定的最准确方法,且选用的协同消解剂,消解完全,对二磷酸哌嗪有很好的选择作用.
Abstract
The potassium persulfate nitric acid digestion method was used to digest the phosphorus in piperazine diphosphate.After digestion,the solution was precipitated with a quinomyoximone precipitant,and the precipitate was dried and weighed to calculate the phosphorus content.This method has high accuracy and good reproducibility,making it the most accurate method for the determination of constant phosphorus content.The selected synergistic digestion agent has complete digestion,making it a good choice for piperazine diphosphate.
