Impregnated Carbons for the Adsorption of H2s and Mercaptans
Activated carbon has been used for many years for the adsorption of H2S and Mercaptans from natural gas streams, carbon dioxide, and sewage vents. It is widely thought that the carbon pore surface catalyses the oxidation of HzS to elemental sulfur and higher oxidized forms of su l fd2 . However, due to the poor loading capacities achieved at ambient conditions, most commercial activated carbon ...
متن کاملTHE IODOMETRIC DETERMINATION OF CYSTlNE IN THE URINE
The iodometric titration of thiol compounds, first introduced by Rosenheim and Davidsohn (1) and modified by Klason and Carlson (2), was applied to the determination of cysteine and related compounds by Okuda, who studied the reaction of cysteine with iodine in acid solution (3). The reaction would be a valuable one if the conditions for the conversion of -SH to -SS(cysteine to cystine) could b...
متن کاملIodometric and colorimetric methods for the estimation of calcium in serum based on the use of an improved permanganate solution.
In a previous paper (Loureiro a Janz, 1942) we compared the iodometric and oxalic acid titres of permanganate solutions under various conditions, and verified that the values obtained in titrating small samples of oxalic acid in the usual way in hot dilute acid solution may differ appreciably from those yielded by the permanganate-iodide-thiosulphate reaction. This merely confirms a well-known ...

متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
