【Abstract】 It is an important part of production process analysis that content of porous ammonium nitrate coating is determined.In this paper,through discussion on some flaws in former analysis procedure,the most appropriate extractive solvent and the optimal extraction conditions are determined,vacuum filtration equipment is refitted.Extraction rate surpassed 90%.Recovery rate determined by adding a standard material reached 95% and is higher than former analysis procedure.The new procedure have advantages that its operations of apparatuses are simple and its accuracy is high,results are satisfactory in industrial production.更多还原
