Effect of Ca2+, Ba2+, and Sr2+ on Alginate Microbeads

Generally, a lot of bi- and trivalent cations can be used for the gelation, although the gel strength varies depending on the cation. For example, Fe2+, Fe3+, Pb2+, Cd2+ and Cu2+ also lead to a gelation. Calcium is usually used because it is non-toxic.
