“…[16] It is known that polymers containing carboxylic acid groups form ionic bonds with the metal surface and this reduces the polymer desorption. [19] Kislenko and Verlinskaya showed that polymers containing active functional groups such as PAA can be adsorbed on the zinc oxide, interact with them to form complexes then desorp and thereby increase the zinc ion concentration in solution. [19] Similarly, the effect of anionic dispersing agents on the solubility of kaolin was studied by Zaman and Mathur.…”

[20] They proved that concentration of the aluminum and silicon ions in kaolin suspensions is highly affected by the dosage of the dispersing agents and the slurry pH.…”

In this study, solubility behavior of lead magnesium niobate (PMN) powders in water was investigated in the presence of pure polyacrylic acid and polyacrylic acid/polyethylene oxide comb polymers. Experiments were performed by measuring the solubility of PMN in terms of the concentration of Pb þ2 and Mg þ2 ions in supernatant as a function of pH and dispersing agent dosage. The concentrations of the metal ions in supernatant were found to be affected by the dispersant concentration, stirring time and the suspension pH. Results revealed that both dispersing agents enhance the cation dissolution from PMN surface at pH 9 due to weak (reversible) adsorption and complexation of Pb þ2 and Mg þ2 by carboxylate groups. On the other hand, under acidic conditions cation dissolution from PMN is inhibited and this was attributed to the strong adsorption of dispersing agents onto the powder surface and formation of a dense polymer layer.
