| 摘要 |
FIELD: analytical chemistry; methods for concentrating aqueous solutions; water analyses. SUBSTANCE: method comprises step of passing water through granulated inert inorganic carrier impregnated with organic solvent, followed by step of removing solvent together with organic compound to be concentrated by heating carrier in inert gas flow, with subsequent condensation of evaporated substances. Method employs solvent having greater solubility in water than compound to be concentrated. EFFECT: efficient approach for concentrating organic matter from water. 2 cl |
