This study used methanol as extraction solvent and eluent, using XAD-4 macroretcular resin as adsorbent, using gas chromatography - mass spectrometer, respectively assayed the organic components of panax rhizosphere soil, panax root exudates and decomposed panax products, the results showed: rhizosphere soil were effectively identified seven kinds of components, and panax root exudates were identified...
A trace analytical method of o-chloropheno, chlorobenzene and ethylbenzene in water had been developed by using salting-out phase separation microextraction coupled to high performance liquid chromatography. A Diamonsil C18 column (5μm, 250×4.6mm i.d.) was used for separation at 30°C with detection wavelength at 220nm; The mobile phase was a mixture of methanol and water (the ratio of volume was 53:47),...
A environmentally friendly and powerful technique was used for determination of parathion in water samples using hollow fiber supported liquid phase microextraction (LPME) followed by high performance liquid chromatography (HPLC). Some effective parameters on extraction, such as extraction solvent, pH of donor phase, extraction time, extraction temperature and stirring speed were investigated. Under...
