| 内容記述 | The effect of the poly(oxyethylene) (POE) chain length of ionic surfactants, expressed as C_12 H_25 -(-OCH_2CH_2-)- n OCH_2 C_6 H_3 (OH)(NO_2) (n = 2-9), on the extraction of monovalent cations, including alkali metal and tetraalkylammonium (TAA) ions, was investigated. The extraction constants (K_<ex>) with surfactants having a POE chain of n ≧6 were almost constant for each alkali metal ion. The K_<ex> sequence was Li^+ < Na^+ < Cs^+ ≦ K^+ = Rb^+. The extractability and selectivity largely decreased as n in the surfactant decreased (n < 6). The effect of the POE chain length was related to the stability of the alkali metal-POE complex. Unlike an alkali metal ion, the K_<ex> values for all TAA ions were almost constant with surfactants of n = 2-8. These facts indicated that the surfactant extracts alkali metal ions by both complex formation with its POE chain and ion-pair formation with a terminal p-nitrophenolate anion. On the other hand, TAA ions were extracted simply by ion-pair formation with a p-nitrophenolate anion of the surfactant. The proposed structures are discussed from the viewpoint of the spectrum shift of the extracted species. | |||||
