研究了非离子表面活性剂Triton X-100在聚乙烯基甲醚凝胶(PVMEG)上的变温柱吸附。Triton在再生PVMEG上的吸附速率和吸附量与原始凝胶上的基本相同。PVMEG的再生只需将温度移至转变温度以下，然后用少量无Triton的溶液冲洗解吸的Triton即可。由于这一独特的再生特性，吸附物的浓缩是可能的。解吸过程中的最大Triton浓度比前一次吸附过程中进柱的Triton浓度大7倍以上。
The temperature-swing column adsorption of nonionic surfactant Triton X-100 with poly-(vinylmethylether) gel (PVMEG) was investigated. The adsorption rate and adsorbed amount of Triton on the regenerated PVMEG were almost the same as those on the virgin gel. The PVMEG was regenerated simply by shifting temperature below the transition temperature followed by flushing out the desorbed Triton with a small amount of Triton-free solution. Because of this unique regeneration feature, the concentration of adsorbate was possible. The maximum Triton concentration in the desorption process was more than 7 time larger than the Triton concentration fed to the column in the preceding adsorption process.
