Trivalent metallic cations for coagulation?

17 August 2017 1 9K Report

Does anybody know if using a water soluble salt that generates a trivalent metal cation rather than a divalent cation for sodium alginate coagulation has any impact on the mechanical properties (increases the structural integrity) of the polymer product (i.e. more cross-linking than calcium salts due to higher valency)?

William Peer

Al2(SO4)3 does an excellent job of coagulation in general; I expect it is much better than a calcium salt.
