摘　　要：建立了石墨炉原子吸收法测定肼类推进剂中锌、铁、铬、锰、铅、镍、铝、铜、钛等金属含量的检测方法 ,无需样品预处理过程 ,灵敏度高且快速、准确。各元素测定方法的精密度小于 1 0 % ,回收率在 82 %～ 1 1 6%之间。A method for determining Fe, Zn, Cr, Mn, Pb,Ni,Al,Cu,Ti in the propellant of hydrazine compounds by graphite furnace atomic absorption spectrometry was established. The pretreatment of samples was not needed. The relative standard deviations were below 10% and the recoveries by standard addition were in the range of 82%～116%.
