The sulphides of the alkali metals and of the alkaline earth metals are readily decomposed by weak acids, even by carbonic acid.3 Ily the use of these sulphides and dilute sulphuric acid it is possible to obtain hydrogen sulphide in a high degree of purity. The hydrosulphides of the alkaline earth metals arc convenient sources of hydrogen sulphide, yielding the gas on treatment with carbon dioxide or even by merely heating.4 The carbon dioxide method is applied on a technical scale in the extraction of sulphur from alkali waste (see p. 50).

Carbon Dioxide Absorption Method. Another commonly employed chemical technique is the absorption of carbon dioxide into a mild alkahne or an appropriately buffered solution (Andre et al., 1981). The carbon dioxide method is similar in principle and procedure to the sulfite oxidation method. Chisti (Chisti, 1989) indicated that the limitations for this method were similar to those of the sulfite oxidation method. 

In fact, desolvated or activated samples (e.g., the supercritical carbon dioxide method), exchange of guest particles (including molecules, cations and ions) from host materials, " micropatterning [i.e., introduction of large guests or the formation of metal nanoparticles ), building block replacement etc. have all been performed in a post-... 

There is conjecture about the existence and identity of a moiety secondary to the C-6 carboxylic acid group due to the disparity between carboxyl titration and carbon dioxide generated from oxidized cellulose. While carboxyl titration measures the carboxylic acid content of the oxidized cellulose, the carbon dioxide generated reflects the total carbonyl moieties. The carbon dioxide method results in a higher carbonyl content than is reflected in the carboxyl titration method (Unruh et al., 1947). ... 

In aalt-aaturated reagents, 97.5% of the theoretical nitrogen was obtained either with or without the hydraxine technique (603). The titrunetrio-carbon dioxide method yielda only 05% of the theoretical CO. in 15 minutes at 110-115 C. (165). MacFadyen (547) found 86% of the theoretical nitrogen in 8 minutes at pH 2.5 by his ammonia method while Sobel et al, (743) obtained 1002% of ammoni nitrogen in 10 minutes at pH 26 and 100°C.
