47. Chromium VI compounds 1. Cement and cement-containing mixtures shall not be placed on the market, or used, if they contain, when hydrated, more than 2 mg/kg (0,0002 %) soluble chromium VI of the total dry weight of the cement. 2. If reducing agents are used, then without ...
The initial nitrate concentration (mg L−1) in the tab water was ~ 0.01, while that in the polluted groundwa- ter used in the present study was ~ 0.41. Nitrate in water is highly soluble because it can cause eutrophication in aquatic systems, and hence is considered a ...
Complex 1's reaction with 23 equivalents of sodium or potassium yielded chromium complexes incorporating dinitrogen ligands, bridging the chromium ion and the alkali metal ion; examples include [CrNa(LBn)(N2)(Et2O)2] (2) and [CrK(LBn)(N2)4(Et2O)2] (3). Posted in Uncategorized | Leave a...
