摘要: Ions play critical roles in reactions of biological, environmental, and industrial importance under frozen conditions. Transfer voltammetry tetramethylammonium (TMA) K+ ions is measured at the interface between aqueous NaCl dichloroethane to give an insight into chemistry phases. The ion-transfer current TMA initially increases as temperature becomes lower from freezing point, but further decrease reduces transfer current. half-wave potential shows a negative shift when liquid phase volume smaller than 10 % total phase. Similarly, facilitated by crown ether complexation also with decreasing temperature, due freeze concentration
