Glycerine-NaCl-H2O-Cation Exchanger계의 이온 배타 평형
Ion Exclusion Equilibria for the System Glycerine-Sodium Chloride-Water-Cation Exchanger
초록
Amberite IR 120 과 Diaion SK 1B를 사용한 Glycerine-NaCl-H2O계에 있어서 Glycerine 0∼60 wt%, NaCl 0∼6 wt%일 때 계의 조성과 온도가 이온 배타 평형치에 미치는 영향을 고찰하였다. 그 결과 25 ℃에서의 평형은 NaCl의 농도가 감소할수록 이온 배타의 효과가 증가함을 알았고, Glycerine 농도는 Amberite IR 120일 경우 40∼50 wt%, Diaion SK 1B의 경우 30∼40 wt%일 때 최대 분배계수를 얻었다. 또한 온도 영향은 Amberite IR 120은 40∼50 ℃에서 Diaion SK 1B는 20∼30 ℃에서 최대가 되었다.
Ion exclusion equilibrium of glycerine-sodium chloride-water system was studied using Amberite IR 120 and Diaion SK 1B. The effects of temperature and component concentrations, glycerine concentrations varying from O to 60 wt% and NaCl concentrations being 0, 2, 4, and 6 wt%, on the equilibrium were observed. At 25 ℃, ion-exclusion increased with decreasing NaCl concentration.
Maximum distribution factor of the system was observed at glycerine concentration of 40∼50 wt% and at 40∼50 ℃ when Amberlite IR 120 was used, and at glycerine concentration of 30∼40 wt% and at 20∼30 ℃ when Diaion SK 1B was used.
