A novel liquid membrane system,denoted as strip dispersion hybrid liquid membrane(SDHLM),containing N_(902) in kerosene as carrier,was studied as the function of dodecanol concentration,pH in feed phase,volume ratio between stripping solution and organic phase,and circulating flux of feed phase or strip dispersion phase.

Determination of trichlorobenzenes in water-based cutting fluids and wastewater of machining using dispersive liquid-liquid microextraction-gas chromatography/mass spectrometry

A simple,rapid and effective method,the dispersive liquid-liquid microextraction coupled with high performance liquid chromatography-fluorescence detection(DLLME-HPLC-FLD),has been developed for the extraction and determination of polynuclear aromatic hydrocarbons(PAHs) in environmental water samples.

Determination of trace vanadium in water samples with dispersive liquid-liquid microextraction(DLLME)-digital colorimetry(DC) was investigated.

Dispersive liquid-liquid microextraction(DLLME)is a novel environmentally benign sample-preparation technique,possessing obvious advantages of simplicity of operation,low-cost,high enrichment factor and low consumption of organic solvent.

A novel method was developed for the determination of chlorothalonil,captan and folpet in grape samples by dispersive liquid-liquid microextraction(DLLME) coupled with gas chromatography-electron capture detection(GC-ECD).

In this article,the basic principles and the latest applications of two liquid phase microextraction techniques,liquid phase microextraction based on porous hollow fiber and dispersive liquid phase microextraction are introduced.
