Uptake of Benzene and Alkylbenzenes by Cation- and Anion-Exchange Resins from Aqueous Solutions 實政, 勲 實政, 勲 Sanemasa, Isao サネマサ, イサオ 實政 Sanemasa サネマサ 勲 Isao イサオ © 2006 The Japan Society for Analytical Chemistry. 433 application/pdf 論文(Article) Uptakes of benzene and 12 alkylbenzenes (from toluene to tt-pentylbenzene including xylene and trimethylbenzene isomers) by both strong acid cation (Dowex 50W-X4 and X8) and strong base anion (Dowex 1-X4 and X8) exchange resins have been studied in aqueous solutions at 25°C; their distribution constants (AT) have been determined. The relationship between the octanol-water partition coefficient (K<m) and the resin affinity for solutes has been analyzed. The K values of benzene and alkylbenzenes were larger than the K values of aliphatic hydrocarbons expected from the Kim values. While the K value was increased with the alkyl chain length, no further increase in the K value was observed for w-butylbenzene and /i-pentylbenzene. http://www.jsac.or.jp/cgi-bin/analsci/toc/ 日本分析化学会 2006-06 eng journal article VoR http://hdl.handle.net/2298/10916 https://kumadai.repo.nii.ac.jp/records/22173 10.2116/analsci.22.899 09106340 http://hdl.handle.net/2298/10915 AA10500785 Analytical sciences 22 6 899 901 https://kumadai.repo.nii.ac.jp/record/22173/files/0910-6340v22_899.pdf application/pdf 358.1 kB 2020-03-02
