【 摘 要 】

References(6)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.
