been tested in adsorption experiments from water solutions of different
concentrations. Additional experiments were carried out to evaluate these
materials as active phase of electrochemical sensors for heavy metal detection.
For instance, the anodic signals obtained after preconcentration of the electrode
based on cationized HPMC-Cloisite in Pb 2+ or Cd 2+ indicate the retention of
these ions by this bionanocomposite, and so the modified electrode could be
useful for the quantitative determination of those pollutants.
