Sodium alginate is soluble in both cold and hot water and it produces a colloidal solution. The viscosity of this solution is measured by a viscometer. Viscosity is affected by the molecular weight of the sodium alginate polymer.
Viscosity changes are dependent on the degree of polymerization of the uronic acid units, the molecules which comprise alginic acid. When the molecular weight is high, the viscosity is high even at low concentrations. The viscosity decreases as the molecular weight decreases. Aqueous sodium alginate solution exhibits smooth flow properties; the closest to Newtonian behavior amongst the natural hydrocolloids.
These flow properties can also be adjusted to thixotropic behavior by the addition of a small amount of calcium salt. Sodium alginate is used as a thickener in various foods by combining these behaviors. When contacting a calcium salt with a sodium alginate solution, it forms a gel instantly. By utilizing this function, jelly molded into spherical or spindle-shapes can be created and these are used to make imitation foods such as salmon roe or shark fin. Calcium ions can be chelated with phosphates to delay the reaction with sodium alginate or, conversely, acid can be used to accelerate the reaction by promoting the ionization of calcium ions.
Conclusion: The supplement promoted fecal excretion of what is likely ongoing low-level exposure via ingestion. This is the first report of a supplement promoting uranium excretion suggesting it may reduce negative health effects in regions where chronic uranium exposure is known.

Alginate extraction process is carried out in an alkaline atmosphere addition of Na2CO3 solution , because alginate is soluble in base and insoluble in acid. Algae are washed, then dissolved in alkali, namely sodium carbonate solution.
After the cellulose is lost, the alginate can be separated by precipitation in the form of calcium salt or alginic acid. When the result of calcium alginate, the precipitate should be washed with acid so that the result turned into alginic acid, then added base to obtain the desired type of salt. Generally alginate manufacture consists of selection, cutting, immersion, precipitation and purification.
Alginate is usually used in the form of salts such as Sodium salt, Calcium, Potassium and Ammonium and also in the form of esters such as Propylene glycol alginate. Sodium alginate is a sodium salt of alginic acid. The empirical formula is NaC6H7O6.
