Wastewater is a challenging matrix for extraction with a liquid/liquid approach. Solid phase extraction (SPE) eliminates emulsions and can result in a smaller extract, saving evaporation time and solvent emissions.
The US EPA is moving towards adding SPE to wastewater methodology, increasing the suite of methods that already incorporate modern SPE technology for drinking water, surface water and groundwater. For a more detailed description of US EPA method 625 for semi-volatiles in wastewater, hear the webcast of the recently presented paper on this topic. Solid phase extraction gave excellent recoveries and precision for both 100-mL and 1000-mL synthetic wastewater samples.

Solid-Phase ExtractionSolid-phase extraction (SPE) is used for clean-up, extraction and concentration of semi-volatile or non-volatile analytes from complex mixtures including blood, urine and food samples. Multiple formats are available for conducting SPE, including prepacked SPE cartridges, disks and microplates, as well as SPE sorbent powders for manual packing. SPE systems can be used to automate the process and extract multiple samples at once. Solid-phase microextraction (SPME) and supported liquid extraction (SLE) products are also available in the same formats.
