Electrochemical cell for determination of hydrogen sulfide in a gas mixture: Electrochemical cell for determination of hydrogen sulfide in a gas mixture. Petersen, Otto; Schmidt, Hans Dieter (Bayer A.-G., Ger.). Ger. Offen. DE 2657570 22 Jun 1978, 6 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: G01N027-46. APPLICATION: DE 76-2657570 18 Dec 1976. DOCUMENT TYPE: Patent CA Section: 59 (Air Pollution and Industrial Hygiene) Section cross-reference(s): 79 The electrochem. cell has Ag/Ag2S working and ref. electrodes and Cu sheet auxiliary electrodes surrounded by a PbO2 electrolyte. The electrolyte for the working electrodes is a gel-type sheet of poly(vinyl chloride) [9002-86-2] 10-20, propylene carbonate [108-32-7] 20-30, di-Et phthalate [84-66-2] 20-30, and potassium hexafluorophosphate [17084-13-8] ~1 wt.%.

The double layer at the mercury/acetone interface at large positive charges: The double layer at the mercury/acetone interface at large positive charges. Borkowska, Zofia (Inst. Phys. Chem., Pol. Acad. Sci., Warsaw, Pol.). J. Electroanal. Chem. Interfacial Electrochem., 79(1), 206-10 (English) 1977. CODEN: JEIEBC. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 66 The elec. double layer in acetone [67-64-1] was studied by capacitance measurements, and the accessible potential range in solns. of several weakly adsorbed electrolytes was established. The double layer capacitance curves were plotted in 0.2M KPF6 [17084-13-8], LiNO3 [7790-69-4] and 0.1-1M NaClO4 [7601-89-0] solns. using an a.c. Schering type impedance bridge. Zero-charge potentials were detd. for each soln. using a streaming Hg electrode. Potentials were measured vs. an aq. 1M LiCl calomel electrode. Addnl., the half-wave potential of cobalticinium in each soln. was measured. Acetone is another org. solvent with a low dielec. const. in which a water-like capacity hump was found at potentials pos. of the point of zero charge. As for many other org. solvents, the preferred orientation of the acetone dipole is with its pos. end towards Hg. Solvent reorientation phenomena are possibly responsible for the hump. However, at such pos. potentials, some sp. adsorption of anions likely occurs and the acetone hump is possibly of soln. ionic nature.
