| 摘 要： | 采用氢气还原金属钼粉中的氧，以无水甲醇作吸收液，吸收还原产生的水，应用气相色谱法测定吸收液中水的含量以确定金属钼粉中可被氢还原氧的含量。结果表明，本法测定结果与国标方法测定结果基本一致。方法适用于中小型企业实际生产中金属粉末中氧含量的常规测定。

| Abstract: | A method for the determination of oxygen in powder molybdenum with gas chromatography is described. The oxygen in metal powder such as molybdenum powder is reduced to water with hydrogen and absorbed by methanol, then by detecting the water in methanol with gas chromatography, the oxygen content in sample can be got conveniently. As results shows the method simple, rapid and practical in the determination of oxygen in metal powder. |
