Determination of Carbon Monoxide

Carbon monoxide is highly toxic because it has a higher affinity for hemoglobin than does oxygen. CO sensors are therefore of utmost importance for combustion control, fire-alarm systems, and detection of hazardous concentrations of the gas in private and industrial facilities such as tunnels, coal mines, and underground garages. The sensors in current use, in which CO is anodically oxidized or adsorbed onto coated piezoelectrodes, are relatively nonspecific, since H2S, N2O, and NO2 interfere. [Pg.155]

Hill et al. (1981) proposed a CO sensor based on inhibition by the gas of cytochrome oxidase (EC 1.9.3.1) coupled to a modified platinum electrode via cytochrome c. This type of sensor has been further improved by Albery et al. (1987a). [Pg.155]

Carbon monoxide oxidoreductase has been employed by Turner et al. (1984) in an attempt to construct a novel CO sensor. The enzyme, which was isolated from Pseudomonas thermocarboxydovorans, has a molecular weight of 270 000 and contains FAD, FeS, and molybdenum as redox active groups. It catalyzes the oxidation of CO to CO2 using various electron acceptors, e.g. NMP+ or oxygen. The temperature optimum of the raction is 80°C. The KM value for CO is as low as 0.5 pmol/1 acetylene and cyanide inhibit the enzymatic reaction. [Pg.156]

In principle, this sensor is also applicable to CO measurement in the gas phase for it was possible to keep the enzyme stable in a wet medium behind the gas-permeable membrane. In comparison with other biocat-alytic gas-sensing devices, e.g. those for methane (Karube et al., 1982a) or NH3 and NO2 (Hikuma et al., 1980b) the sensor was more compact and its response was substantially faster. This enzyme electrode therefore represents a promising approach to novel gas sensors. [Pg.156]

It is possible to estimate the influence of the spectrometer on linewidth measurements by convolving the response function with a mathematical model of the line. The resulting curve may be compared with the observed line and the true width inferred. Hunt et al. (1968) have employed corrections of this type supplied by the author in their determination of carbon monoxide self-broadened linewidths. [Pg.31]

Complexes of phenanthroline and palladium(II) chloride react with carbon monoxide in aqueous solution to give the stable violet compound [(phen)Pd(C0)2Pd(phen)] 4H20 bipyridyl gives an unstable product (119). The formation of the compound has been suggested as the basis of an analytical method for the determination of carbon monoxide (118). [Pg.194]

OTHER OXIDANTS Pickering reviewed the use of solid oxidants in analysis. He included C (/7) oxide for Dumas nitrogen, iodine pentoxide for oxidation and determination of carbon monoxide, and Mn(JV) oxide at 350°C for gas-solid reactions. [Pg.311]

Continuous determination of carbon monoxide and carbon dioxide in the flue gas, by means of an infrared gas analyzer, has been reported to be an effective method for operating control, as well as for calculation of yields (307). [Pg.301]
