Hazardous compounds are chemically treated to remove various pollutants by subjecting the compounds (samples) to various process steps, including selecting specific solvents and using them, treating the sample at room temperature or below (30 DEG C or lower); separating fatty acids mixed with heavy metal and semi-metal compounds as well as the separation of organic substances (including halogenated compounds) added to heavy metals and semi-metals; and using sodium nitrite and sodium 1-naphthylamine-4-sulfonate in combination from specific solvents, thereby forming alkylsulfonic acid salt and alkyl sulfonium salt in the presence of sulfonic acid salt so as to fix organic substances mixed in the sample. |
