摘要
Abstract
A green pretreatment method combining sealed infrared heating digestion technology with chemical ab-sorption of acid fume was used to wet decompose and pretreat solid propellant samples that require determination of inorga-nic component content,and absorb harmful acid fume generated by the reaction.The results show that during infrared hea-ting nitration,the content of combustion catalyst in the propellant meets the requirements by preheating for 5 min at 10%power of the electric furnace,heating for 30 min at 30%power,and then continuously heating for 40 min at 70%power.After preheating with an electric furnace at 10%power for 5 min,heating at 30%power for 30 min,and then continuously heating at 50%power for 60 min,the content of carbon black in the propellant meets the requirements.Zero emission of acid fume was achieved through two-stage absorption using alkaline solution with a mass fraction of 30%.The method is easy to operate,with high accuracy and precision,and can be used for sample pretreatment in the determination of inorga-nic component content in solid propellants.关键词
