✦ Synopsis
Electrostatic phenomena in chelating resins containing formazan derivatives were studied by measuring streaming potentials. It was found that the adsorption of metal ions can be related to the chelation due to proton replacement in the low pH region whereas it will be changed to adsorption due to electronegativity in the neutral pH region. The electrostatic potentials in the resin phase vary with metal chelation of the formazan groups. Metal chelation lowers the electrostatic energy, enhancing the stability of the resins.
