A non-dispersive extraction technique,using an emulsion liquid membrane within a hollow-fiber-contactor for the extraction and enrichment of Nd~(3+) from the dilute feed aqueous,was applied.

Study on decoloration of concentrated wet-process phosphoric acid by predispersed solvent extraction technique;

The progress of the research in colloidal liquid aphrons(CLAs) has been reviewed,which includes the preparation,structure,stability of colloidal liquid aphrons(CLAs) and its applications in separation engineering,especially in predispersed solvent extraction(PDSE).

The use of colloidal liquid aphrons in predispersed solvent extraction may ameliorate the problems such as emulsion formation,reduction of interfacial mass transfer and low interfacial mass transfer areas in solvent extraction process.

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).

Determination of triadimenol residue in foods with dispersive solid phase extraction cleanup by gas chromatography-negative chemical ionization mass spectrometry;
