초록

Sulfonated oligo(p-phenylene sulfide) (SOPS) 이온교환체에 대한 금속이온들의 분포계수와 알칼리금속(Li, Na, K)의 피크레이트염과의 이온결합능에 대하여 알아보았다. 그 결과, 분포계수는 알칼리금속의 경우 Li(I)b값은 더 커지고, 금속의 원자번호가 증가함에 따라 Li(I)

Distribution coefficient (K_d) of metal ions and ion binding ability of alkali metal (Li, Na, K) picrates on sulfonated oligo (p-phenylene sulfide) (SOPS) ion exchanger was studied. Distribution coefficient (K_d) increased in the order Li(Ⅰ)d) increased for strong polarity of solvent, low reaction temperature and increased atom number. In the bonding reaction of SOPS with the metal of alkali picrate, enthalpy (ΔH) and entropy (ΔS) were -0.814 ~ -1.304 kcal/mol and 12.468 ~ 14.207cal/K·mol respectively. It was spontaneous reaction due to the negative value of Gibbs's free energy.

Keywords:thermostable ion exchanger;sulfonated oligo (p-phenylene sulfide);metal ions binding constant;distribution coefficient
