在1948年我们即曾提出:应用快速燃烧的原理,在测定碳与氢时,具有同时测定硫的可能性。僅须取用一个试样,重约4—6毫克。这些燃烧的产物分别用管子吸收,在测定碳与氢时,也可同时测定存在於试样中的硫。硫的燃烧产物系用金属的银在特制的仪器中吸收起来,将此装有银的吸收器经过称重以后,即可准确地得知SO_4的重量,然后从换算因数S/(SO_4)=0.3333,可以算出试样的含硫百分数。金属的银和硫的氧化物,定量的生成Ag_2SO_4这反应的历程如何,至今尚不能阐明。
In 1948 we immediately proposed: the principle of rapid combustion, the determination of carbon and hydrogen, with the possibility of simultaneous determination of sulfur. Just take a sample and weigh about 4-6 mg. The products of these combustion are respectively absorbed by the pipe. In the measurement of carbon and hydrogen, the sulfur present in the sample can be simultaneously measured. Sulfur combustion products with silver metal in a special instrument absorbed up, after this silver-loaded absorber weighing, you can accurately get the weight of SO_4, and then from the conversion factor S / (SO_4) = 0.3333, you can calculate the percentage of sulfur content of the sample. Metallic silver and sulfur oxides, the quantitative formation of Ag_2SO_4 This reaction process, so far still can not be elucidated.
