Solid phase extraction and thermal desorption of acetophenone and m-cresol using superheated water or steam as the sole eluent
Joanne R. Bone and Roger M. Smith
Steam or superheated water can be used to efficiently elute moderately polar and non-polar compounds from polymeric sorbents at temperatures up to 220 °C without degradation of the analyte. Acetophenone and m-cresol, as model compounds, have been concentrated from dilute aqueous solutions, using solid phase extraction (SPE) traps packed with polystyrene–divinylbenzene (PS–DVB) or poly(divinylbenzene-co-N-vinylpyrrolidone). The technique offers low cost, ease of use and an environmentally friendly eluent.
