so2 DETERMINATION HAUG

IntroductionExperimentalResults and DiscussionConclusionsSodium alginate is a purified carbohydrate product extracted from brown seaweeds. It primarily consists of sodium salt of alginic acid, which is a mixture of polyuronic acids composed of residues of β-D-mannuronic acid (M unit) and α-L-guluronic acid (G unit) linked together through a 1 → 4 glycosidic linkage, as shown in Fig. 1 (1). Alginates and alginic acid are widely used in the food industry, biotechnology and medicine because of their gel-forming capacity. The behavior of alginate is stronglySee more on academic.oupLiquid-Phase Composition Determination in CO2−H2O ...+Nov 10, 2005NMR studies were performed investigating the liquid-phase composition in samples where various amounts of CO2 were dissolved in aqueous alkanolamines (butyl-ethanolamine (BEA), methyl-di-ethanolamine (MDEA), and monoethanolamine (MEA)) at various temperatures. Chemical shifts of functional groups present in the systems were determined, and the liquid-phase compositions
