摘　　要：建立了利用气相色谱外标法测定AlH3中乙醚含量的方法。分别采用水解法、NaOH滴加法、液上气相法、固上气相法对AlH3样品进行前处理,将上述方法对比后选用固上气相法处理AlH3样品。AlH3样品经固上气相前处理后利用气相色谱外标法测定其乙醚含量,该方法具有重现性好、标准偏差小等优点。Determination methodofether content in AlH3 using gas chromatography external standard method was established. AlH3 samples were pretreated separately by hydrolysis method, sodium hydroxide titration method, headspace gas phase method and solid-head gas phase method. After comparing above-mentioned methods, solid-head gas phase method was selected to pretreat AlH3 sample. The ether content in AlH3 sample after pretreatment by solid-head gas phase method was determined by gas chromatography external standard method. This method has the advantages of good repeatability, low standard deviation, etc.
