Sodium alginate Usage And Synthesis
DescriptionSodium alginate is the sodium form of alginate. Alginate is a linear, anionic polysaccharide consisting of two form of 1, 4-linked hexuronic acid residues, β-d-mannuronopyranosyl (M) and α-l- guluronopyranosyl (G) residues. It can be arranged in the form of blocks of repeating M residues (MM blocks), blocks of repeating G residues (GG blocks), and blocks of mixed M and G residues (MG blocks). Commercially available alginate currently originates from algae. Alginate has wide applications. For example, one of its most important role is being used as wound dressing materials for the treatment of acute or chronic wounds. The use of alginate crosslinking to make hydrogels for cell encapsulation is also quite valuable. The emergence of various kinds of its derivatives recently has further extended its application.
Chemical PropertiesColorless or slightly yellow solid occur- ring in filamentous, granular, and powdered forms. Forms a viscous colloidal solution with water; insoluble in alcohol, ether, and chloroform. Com- bustible.
HistorySodium alginate is a natural polysaccharide product that was first described in a patent application by the British chemist Edward C C Stanford in 1881. To this day brown algae are still the main source used to extract sodium alginate from. This group includes many of the seaweeds, like kelps, found in chilly northern seas. In addition to the food industry, the gelling properties of sodium alginate have been used in medical, dental and cosmetic applications for years.
  1. 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.
  2. 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.
  3. 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.
    The polymer can be represented like this:
    Sodium alginate
    When sodium alginate is put into a solution of calcium ions, the calcium ions replace the sodium ions in the polymer. Each calcium ion can attach to two of the polymer strands. This is called cross-linking and can be represented like this:
    Calcium alginate
UsesIn the manufacture of ice cream where it serves as a stabilizing colloid, insuring creamy texture and preventing the growth of ice crystals. In drilling muds; in coatings; in the flocculation of solids in water treatment; as sizing agent; thickener; emulsion stabilizer; suspending agent in soft drinks; in dental impression preparations. Pharmaceutic aid (suspending agent).
Purification MethodsFree it from heavy metal impurities by treatment with ion-exchange resins (Na+-form), or with a dilute solution of the sodium salt of EDTA. Alternatively dissolve it in 0.1M NaCl, centrifuge and fractionally precipitate it by gradual addition of EtOH or 4M NaCl. The resulting gels are centrifuged off, washed with aqueous EtOH or acetone, and dried under vacuum. [Büchner et al. J Chem Soc 3974 1961.] Sodium n-alkylsulfates. Recrystallise these salts from EtOH/Me2CO [Hashimoto & Thomas J Am Chem Soc 107 4655 1985].
