Abstract

Изобретение относитс  к способам , используемьш в аналитической химии, и позвол ет повысить точ ность определени  вюстита в материалах металлургического производства. Способ включает предварительную обработку анализируемого материала 1,0 1 ,1 М раствором уксусной кислоты при кип чении в атмосфере углекислого газа, обработку остатка в атмосфере углекислого газа 3,9-4,1 М раствором серной кислоты в соотноше ™ § а нии с анализируемым образцом 150 200 : 1. СThe invention relates to methods used in analytical chemistry, and improves the accuracy of the determination of wustite in metallurgical materials. The method includes pretreatment of the analyzed material with 1.0 1, 1 M solution of acetic acid at boiling in a carbon dioxide atmosphere, treatment of the residue in an atmosphere of carbon dioxide with 3.9-4.1 M solution of sulfuric acid in relation to the analyzed sample. 150 200: 1.
