Alkaline earth metal oxides optimization

OPTIMIZATION OF ALKALINE EARTH METAL OXIDE Base catalyst... [Pg.287]

Corma A. and Iborra, S. Optimization of alkaline earth metal oxide and hydroxide catalysts for base-catalyzed reactions, Adv. Catal. 2006, 49, 239-302. [Pg.197]

The lead electrode is sensitive to surface oxidation and requires periodical repoHshing. The linear response for the primary cation usually extends from 10 to 10 moll the detection limit is 10 moll . These statements hold only in the optimal pH range of 4—7. At higher pH values the formation of the hydroxides of the divalent metals reduces the upper limit of quantitation. At lower pH the solubility of the sulfides increases and this raises the lower detection limit. The selectivities over alkaH and alkaline earth metal ions are very good. [Pg.2345]
