Relationship between Physical Parameters of Various Metal Ions and Binding Affinity for Alginate.

Abstract

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 Sr2+ was the highest among all tested metal ions. The order of K values was: Sr2+>Pb2+>Tb3+>Dy3+>Ca2+>Cd2+>Mg2+>Fe2+>Fe3+>Co2+>Al3+>Ni2+>Cs+>Cu2+>Ag… (More)
