Alginate has the ability to bind multivalent cations, leading to the formation of covalent bonds and insoluble hydrogels. This anionic polysaccharide forms strong gels with Ca2+, giving microspheres with good strength and flexibility. Such crosslinking stiffens and roughens the polymer, reducing swelling in water and organic solvents (King, A. H.,1983). Alginate has widely used in food and biotechnological purposes such as Gaviscon, Asilone, and Bisodol. For the wastewater treatment in dyeing industry, it is used as an Entrapment immobilizer (Laun et al.,2006).
