SODIUM ALGINATE
To a 0 5 solution of the sample in sodium hydroxide TS add one-half of its volume of a saturated solution of ammonium sulfate No precipitate is formed This test distinguishes sodium alginate from agar, sodium carboxymethyl cellulose, carrageenan, de-esterified pectin, gelatin, carob bean gum, methyl cellulose and starch Test for alginate
Sodium Alginate for Anti-reflux Suspensions – Study of Effect
dictate its solubility in water at neutral pH Alginic acid and calcium alginate are water insoluble forms, whereas sodium, potassium, and magnesium are water soluble at neutral pH Sodium alginate is a linear copolymer composed of β-D-mannuronic acid (M) and α-L guluronicacid (G) linked by 1→4 glycosidic bonds [3]

Characterisation of the degrading properties of alginate
the sodium alginate solution and vortexed for approximately one minute A fresh aqueous GDL solution was then added to the suspension and vortexed for about 30 seconds to initiate gelation The fluid was poured into a 24-wells plate, where complete gelation occurred The complete protocol for the preparation of different alginate samples is given
A STUDY OF SODIUM ALGINATE AND CALCIUM CHLORIDE INTERACTION
The peak for diffraction at around 13º for the sodium alginate increases in the films composed of sodium alginate and calcium chloride, it has great intensity at 2θ=130 (d= 0 657nm) in the ACSI film and it is almost nonexistent in the ACI film This suggests that the interaction between the sodium alginate and the calcium chloride
