Sodium Alginate can be used as a flavorless gum. It is used by the foods industry to increase viscosity and as an emulsifier. It is also used in indigestion tablets and the preparation of dental impressions. Sodium Alginate (NaAlg) and its modified forms have been widely used as membranes in pervaporation (PV) separation of aqueous-organic solutions because of the hydrophilic nature and versatility to modify/tune their structures to achieve the desired separation. Sodium Alginate is a polymer which can be extracted from brown seaweed and kelps. It is one of the structural polymers that help to build the cell walls of these plants. It has some unusual properties and a wide variety of uses.
