Ion‐selective liquid membrane electrodes for Ca2+, CO32−, NH4+, NO3−, NO2−, and pH have been miniaturized and their characteristics evaluated in view of their application in sediment pore water of lakes. PVC membranes were prepared in polyethylene pipette tips with an end diameter of 0.6 mm. This is a simple method to produce inexpensive disposable ion‐selective electrodes for various applications. Detection limits were 1 µM for Ca2+, CO32−, NH4+, and NO3−, and 10 µM for NO2−. The pH sensor was linear in the pH range of 4–11. Selectivities for Ca2+, CO32− and pH are high enough for the application in seawater. The sensors for NH4+, NO3−, and NO2− in their low concentration range experience interferences from K+, SO42+, and HCO3−, respectively, in lake pore water. Reproducibility in pure solutions is between 20.2 and 20.6 mV, The applicability of the miniaturized sensors are demonstrated in measurements of concentration gradients across the sediment‐water interface in sediment cores of several lakes.

“…Examples include B(OTeF& (2), BlICH17-(1, 3), and B k , -(& = C6H5 (4) or 3,5-C6H3(CF3)? (5)). The interest in such species derives in part from a desire to study coordinatively unsaturated cations such as R3Si+ (6) and Fe(porphyrin)+ (3b), both of which have yet to be prepared and isolated in a condensed phase, and in part from the desire to prepare more active transition metal catalysts (4).…”

Addition of B(OTeF,), to TIOTeF, in the weakly coordinating solvents dichloromethane, 1,2-dichloroethane, and 1,1,2-trichlorotrifluoroethane produces solutions of M(solv).,+B(OTeF,),-. When the solvent was 1,2-dichloroethane, the crystalline compound TI( 1 ,2-C2H,Cl2)B(OTeF5), was isolated and studied by X-ray crystallography: triclinic, space group p i , a = 9.221 (4), b = 11.396 (S), c = 12.538 (4) A, cx = 110.75 (3)", P = 101.72 (3)", y = 99.74(3)",Z = 2, T = -116°C. The Tl(1 ,2-C2H,C12)+ cation contains a five-membered chelate ring with T I 4 1 distances of 3.138 (4) and 3.179

Propagation and Synchronization of Potential Oscillations in Multiple Liquid Membrane Systems

Two liquid membrane oscillators composed of aqueous solutions containing cetyltrimethylammonium chloride (CTACl) and alcohol, W1 and W1′, a nitrobenzene solution containing picric acid, O, and pure water phase, W2, were connected through O and W2 as common phases. Two glass tubes including W1 and W1′ were inserted into the O/W2 interface. Both membrane potential differences between W1 and W2 and that between W1′ and W2 were recorded using a pair of Ag/AgCl electrodes located near the orifice of each tube. The oscillations of two membrane potentials synchronized each other when the distance between the tubes was less than 10 mm. The synchronization was attended by the propagation of a potential pulse from one side to another with an interval of approximately 70 ms at a distance of 10 mm. It was examined whether the propagation of the potential pulse was due to electric conduction in bulk phases, or due to the interfacial conduction by several experiments in the addition of indifferent electrolytes or nonionic surfactant. Consequently, it has been demonstrated that the propagation of oscillation pulse was dominated mainly by the interfacial conduction process, and additionally by the bulk ionic conduction and that the interfacial diffusion and distribution of Cl -played a crucial role.
