| titleOfInvention | Method for simultaneous determination of content of fluorine, chlorine, bromine, iodine, sulphur and phosphorus in organic compounds |
| abstract | FIELD: chemistry. n SUBSTANCE: invention describes a novel method for simultaneous determination of content of fluorine, chlorine, bromine, iodine, sulphur and phosphorus in organic compounds by putting a sample of the analysed substance into a stream of oxygen in a reactor at high temperature. The high temperature oxidation products are absorbed with water or eluent which is used for separating anions. Carbon dioxide obtained during the process is blown off from the absorber using a stream of oxygen or an extra stream of inert gas. A small portion of the absorbate is taken to the separation column through a protective column and anions which correspond to the determined elements in the compound in the standard substance via ion chromatography. If necessary, a sample of deionised water which is free from the elements under analysis is fed into the reactor after absorption of the conversion products. Oxidation products are washed from the walls of the reactor into the absorber and the obtained absorbate is analysed. In order to simplify the process, the preferred absorber is a single-use syringe. In case of simultaneous micro-determination of fluorine, chlorine, bromine, iodine, sulphur in organic compounds, a sub-sample is prepared first in form of a solution of given concentration of the analysed substance and the standard substance which does not contain the elements to be determined but contains an element which is not among elements of the analysed substance, in a solvent which does not contain the detected elements. n EFFECT: provision for complete conversion of anions which correspond to the determined elements. n 4 cl, 2 tbl, 2 ex |
