摘要: 本文提出在样品上覆盖Co3O4,用高锰酸银热解产物作催化剂,在550°C燃烧进行燃烧分析的微量测定有机金属化合物中碳氢的方法。燃烧操作时间12分钟,分析结果误差介于±0.3%,由于燃烧温度低,大大延长了石英管寿命。此外,还比较了用各种方法所制备的吸收氮氧化物的MnO2的性能,并选出最佳的制备条件。

Abstract: In this paper, a micromethod for the determination of carbon and hydrogen in organo-metallic compounds has been reported, 3-5 mg of sample was covered with 10 mg of freshly prepared Co3O4 in platinum boat and burned over a catalyst of products of thermal decomposition of silver permanganate under a current of oxygen (25ml/min. ) at 500-550°C. The combustion took about 10 minutes. The data of determination of a series of standard organo-metallic compounds showed that the absolute deviation of this method was within ±0.3%. As a result of low combustion temperature, the duration of the silica combustion tubes was much increased. The properties of MnO2 reagents for absorbing nitrogen oxides prepared by various methods were compared and the procedure for preparing the most effective reagent was described.
