Determination of Carbon Dioxide in Continuous Gas Streams

Abstract

Hydrogen peroxide, made u p in 1.0 N sulfuric acid solution, was found to be stable for as long as 3 weeks. LITERATURE CITED(1) Adie and Wood, J . C h m .

Respiration of Cereal Grains and Flaxseed

“…The titration procedure employed was similar to that used by GURJAR (15). MARTIN and GREEN (18) have shown that spiral absorbers are a very effective means for absorbing carbon dioxide and also that titrating directly in the absorption vessel in the presence of suspended barium carbonate does not cause a loss of carbon dioxide through the decomposition of the carbonate by the acid added during the titration.…”

The Continuous Measurement of Photosynthesis, Respiration, and Transpiration of Alfalfa and Wheat Growing Under Field Conditions

“…The concordance is excellent, not only in full light, but also in cloud shadow, and particularly so considering the fact that plot 5 is a different variety of alfalfa, and the plants are somewhat older. to grow, the plants being [6][7][8] inches high. Part of the plants are shaded early in the morning and late in-the evening by the base of the cabinet, so that the beginning of assimilation is retarded in the morning and its completion hastened in the afternoon.…”

“…Since the atmosphere contains only 310 parts per million by volume of carbon dioxide, the gasometric and gravimetric methods have been handicapped by insufficient material, and the volumetric and electrometric methods have needed more efficient absorbers to permit the use of larger air samples. The latter need recently has been ifiled by the absorbers of MARTIN and GREEV1 (6), HEINICKE and HOFFMAN (4), and THOMAS (9). A unique method of determining carbon dioxide exchange has recently been devised by McALISTER (7).…”

Oxygen Evolution Catalysis with Mössbauerite—A Trivalent Iron‐Only Layered Double Hydroxide

“…For g-Ni-oxyhydroxide ac omparable basal spacing of 6.9 wasr eported, [20,26] whereas for a-Ni-oxyhydroxide a slightly larger basal spacingo f7 .5 was reported, [27] which is more in the line with other carbonate-LDHs (typically 7.5 ), [28] and with that of green rust (7.5 ). Gravimetric analysiso ft he interlayer carbonate content as BaCO 3 [29] indicates al ower carbonatec ontent of M and M-50 as compared to the idealized formula. Assuming that chargen eutrality is assured by adjusting the O 2À /OH À ratio through deprotonation, the following formula can be given for theses ynthetic mçssbauerites: At both temperatures, hexagonally-shaped platy crystals are obtained.…”
