TY - JOUR ID - 874844 AU - Oravec, Michal - Šimek, Zdeněk - Holoubek, Ivan PY - 2010 TI - The effect of humic acid and ash on enantiomeric fraction change of JF - Colloids and Surfaces A: Physicochemical and VL - 2010 IS - 359 SP - 60-65 EP - 60-65 SN - 09277757 KW - Chiral pollutants Enantiomeric fraction Humic acid Ash Liquid chromatography N2 - The aim of the study was to determine changes of enantiomeric fraction (EF) of chiral compounds interacting with components of soil and to describe the effect of amount of soil components on EF value. Soil components (humic acid and ash) were isolated from soil using method recommended by the International Humic Substance Society (IHSS). Dichloromethane was used as an extraction solvent for extraction of polychlorinated biphenyls (PCBs), mecoprop and its methyl ester enantiomers from humic acid (HA) and ash. The extracts were analyzed by a high performance liquid chromatography (HPLC). HPLC columns filled with silica gel modified by permethylated cyclodextrine acting as a chiral selector were used for analytical separation of enantiomers. The results confirm the stereoselective effect of soil components on extractable amount of individual enantiomers. ER -
