  • Patent number: 5958214
    Abstract: The invention relates to an electrochemical sensor to determine the concentration of a gas to be quantified, comprising a housing, a measuring electrode comprising a catalystically active material which causes a reaction of the gas to be quantified, a counterelectrode comprising a carbon material, and a solid electrolyte in contact with the measuring electrode and the counterelectrode, wherein the solid electrolyte is prepared by swelling a solid matrix comprising an acrylate polymer with an electrolytic solution comprising at least one acid, and wherein the carbon material in the counterelectrode has a specific surface of at least 40 m.sup.2 /g and comprises reversibly oxidizable or reducible electrochemically active surface compounds.

  • Patent number: 5730918
    Abstract: Filter material in the form of activated charcoal compacts useful for selectively separating an organic phase from an inorganic phase, is prepared by a process comprising the following steps.A. Homogeneously blending activated charcoal particles having a particle size distribution of 1-100 .mu.m with psuedoboehmite-configured aluminum oxide in a weight ratio of 1:1 to 5:1;B. Adding distilled water to the homogeneous mixture while thoroughly mixing the same;C. Adding dilute acetic acid to the aqueous mixture while thoroughly mixing the same;D. Adding more distilled water to the mixture;E. Compacting the resulting mixture into tablets or similar objects in a mold under pressure, andF. Successively heating the resulting molded objects first at 80-100.degree. C. for 6 to 10 hours, then at 140.degree.-160.degree. C. for 8 to 10 hours, and finally at 180.degree.-200.degree. C. for 6 to 10 hours.

  • Patent number: 5656069
    Abstract: A filter material from active carbon compacts is prepared by the following steps:(a) mixing active carbon powder with polyvinyl alcohol powder in the ratio of 9:1 to 3:1,(b) mixing the powder from step (a) with distilled water or a mixture of distilled water and ethyl alcohol,(c) shaping tablets and similar articles in a mold under pressure, and(d) successively heating the tablets at1) 40.degree. to 80.degree. C. for 3 to 6 hours,2) 80.degree. to 120.degree. C. for 10 to 14 hours.A filter material according to the invention for the selective separation of organic material from an organic phase consists of active carbon compacts thus prepared and is used for the selective separation of organic and inorganic phases.
