Abstract
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.
蒸汽或过热水可用于在高达220°C的温度下有效地从聚合物吸附剂中洗脱中等极性和非极性化合物,而不会降解分析物。苯乙酮和间甲酚,作为模型化合物,从稀水溶液中,使用固相萃取(SPE)陷阱填充聚苯二乙烯基苯(PS-DVB)或聚二乙烯基苯-co- n -乙烯基吡咯烷酮。该技术成本低,使用方便,是一种环保的洗脱液。
