In this study, an efficient and green technique based on ultrasound-assisted extraction was developed for separation and determination of some components of double base solid propellant (DB propellant) by high performance liquid chromatography with UV detection (HPLC-UV-Vis). The optimum extraction conditions with respect to maximum recovery for target analytes were achieved at 120 min, with the power of 800 W for ultrasonic waves and dichloromethane as an extraction solvent for 0.5 gr of DB propellant sample and the recoveries for all component was near to 100%. The results of this investigation under optimum conditions were compared with the result obtained by the Soxhlet extraction method as a routine sample preparation method for DB propellant samples. The results show that the developed method is much faster and sufficient than the traditional Soxhlet extraction method. So, the developed UAE-HPLC-UV method can be used as a rapid and sensitive method for the determination of DB propellants’ constituents.
