liquid-solid extraction

Determination of haloacetic acids and Dalapon in drinking water by ion exchange liquid–solid extraction and gas chromatography with an electron capture detector.

Analytical Methods and Treatment Technology Formaldehyde in drinking water is generally analysed by high-performance liquid chromatography following derivatization with 2,4-dinitrophenylhydrazine and liquid-solid extraction.

This was accomplished by liquid-solid extraction and liquid-gel chromatographic techniques to isolate the phytoestrogen fractions using standard assay methods with internal controls [ 28 ] .

After sediment removal, metolachlor, atrazine and its dealkylated metabolite deethylatrazine (DEA) were extracted using a liquid-solid extraction procedure and analyzed by gas chromatography.
