空气里氧气含量的测定是人教版化学课程教材中一个非常经典的探究实验,教材虽然经过了多次的修订和改版,但始终都是使用红磷作为测定空气里氧气含量的实验药品.笔者在实验时发现,红磷在储存过程中容易潮解,从试剂瓶里取出的红磷往往都是潮湿的,若要把红磷引燃则要花很长的时间,在把燃烧匙中燃着的红磷伸入集气瓶的过程中,产生的P_2O_5不可避免地扩散到空气中.

The determination of oxygen content in the air is a very classic inquiry experiment in the chemistry textbook published by the People's Education Press. Although the textbook has been revised and revised for many times, it always uses red phosphorus as the experimental drug to determine the oxygen content in the air. The author found that red phosphorus is prone to deliquescence during storage, and red phosphorus taken out of reagent bottles is often wet. It takes a long time to ignite red phosphorus, During the process of putting the red phosphorus burning in the combustion spoon into the gas collecting cylinder, P_ 2O_ It inevitably diffuses into the air



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has developed a gas chromatographic method for the determination of oxygen in the air, with high column efficiency, good separation and satisfactory results.
