We investigated the relationship between the physical parameters of various metal ions, including toxic metal ions, and the binding affinity of these metal ions for alginate (Alg). The binding constant, K, of Sr was the highest among all tested metal ions. The order of K values was: Sr>Pb>Tb>Dy>Ca>Cd>Mg>Fe>Fe>Co>Al>Ni>Cs>Cu>Ag>Li>K.

We examined whether calcium alginate (Ca-Alg) reduces blood cholesterol levels in rats fed a high-cholesterol diet. First, we examined taurocholate adsorption in vitro by various types of sodium alginate (Na-Alg). High molecular-weight, guluronic acid-rich Na-Alg showed the greatest adsorption of taurocholate, and therefore the corresponding Ca-Alg was chosen for the in vivo study.
