chitosan, ionic interactions can occur between chitosan and negatively charged
molecules and anions. Ionic complexation of mixed charge systems can be formed
between chitosan and small anionic molecules, such as sulfates, citrates, and
phosphates or anions of metals like Pt (II), Pd (II), and Mo (VI). While
