| Abstract |
An instrumental combustion method was designed for the rapid determination of milligram quantities of phosphorus in aqueous solutions. With this technique both inorganic and organic phosphorus compounds are reduced to phosphine in an hydrogen atmosphere at 920 C. The phosphine is separated from other combustion products on a chromatographic column and measured by a cesium thermionic detector with the signal transmitted to a potentiometric recorder. The method requires microliter samples and the minimum detectability of the system is in the range of 0.1 to 0.2 micrograms (approximately equivalent to 100 to 200 milligrams per liter) as phosphorus. The analysis time per sample is less than 10 minutes. (Author) |
