Actually, the presence of Al 3+ significantly influenced the stability of BMBC . The stability of colloid particles in the aqueous solution and the degree of repulsive electrostatic interaction between the adjacent charged particles can be ... WebThe adsorption is reversible and changes little with pH. This unexpected adsorption behavior of an anionic molecule on an anionic surface is discussed in terms of recent models for surfactant adsorption such as cation bridging, where adsorption has been reported with the divalent ion calcium but not previously observed with monovalent ions. eeo aa officer
