Determination of calcium by atomic absorption spectrophotometry applied to the preparation of alginate:chitosan complexes
(2004-12-01)
Polysaccharicles, as alginate and chitosan, have been used to obtain modified release dosage forms. Alginate, due to its property of building gels during the complex formation with calcium ions, allows the building of ...
