Magnesium ions and alginate do form hydrogels: a rheological …
WebOur study shows that magnesium ions which have so far been considered as non-gelling ions for alginate do induce alginate gelation. Rheology is used to examine effects of alginate chemical composition as well as alginate and magnesium ion concentration. Gelation in this system occurs at ca. 5–10 times higher concentration of ions than reported for … WebMagnesium Ion.
