Abstract
A method for microdetermination of fluorine, chlorine, bromine and sulfur in organic compounds by using a oxygen combustion flask and ion chromatography (IC) was studied. One to 8 mg organic samples were decomposed in the presence of oxygen in a 500 ml quartz flask for fluorine analysis, and a pyrex flask for chlorine, bromine, and sulfur analysis. The combustion products were absorbed in 20 ml of distilled water for fluorine and 20 ml of water containing 100 μl of 1 % hydrogen peroxide solution for other elements. After standing, 5 ml of 20 mM Na2CO3/20 mM NaHCO3solution was added into absorbed solution. This solution was injected into a chromatograph (Yokogawa Hokushin Electric Works, model IC 100) eqquipped with anion analytical column (PAX 1 and SAX 1), cation exchange membrance suppressor and conductivity monitor, and a 4 mM Na2CO3/4 mM NaHCO3 solution was used as a mobile phase. Calibration curves in peak area constructed from the sodium salts of four anions (F-, Cl-, Br-, and SO42-)were linear over a wide range and presented good reproducibility. Single or simultaneous determinations of fluorine, chlorine, bromine, and sulfur in organic compounds resulted within an error of ±0.3 %, which is comparable with those attainable in conventional elementary microanalysis. This method when applied to simultaneous multi-elementary analysis is considered powerful.
