| titleOfInvention | Method for the determination of aromatic and aliphatic hydrocarbons in water |
| abstract | The invention relates to the determination of aliphaticnand aromatic hydrocarbons in waters,ncontaining these substances in concentrations up ton10 g * l-1 in the presence of nitrogennbases, phenols, organic esters andntheir degradation products, chromatographicallynwith internal standard addition. Hisnthe essence is that the stick isnthe analyzed water is acidified with mineral acidnsoluble in water to at least pH = 1nand in a microextraction apparatusnThe liquid phase performs multiple extractionsnwith the number of extraction steps exceedingn1000 of all aromatic and aliphaticnhydrocarbons to a low-boiling solventncompletely immiscible with water forn1 to 10 hours. Extract 0.5 to 10 mlnAqueous solution of alkali hydroxiden* vu selectively shakes phenols and performsnwith chromatographic analysis with additionninternal standard. |
