(a) ζ potentials of CsNPs as a function of pH after the adsorption experiment in 1.0 mM NaCl at pH 6.0 ± 0.1 after 20–24 hours under various conditions: control (open circle), ES + CeNPs (open square), 160 μM P + CeNPs (open triangle), and PS only (open diamond). (b) Average hydrodynamic diameter of CeNPs aggregates as a function of pH after the same adsorption experiments: control (closed circle), with ES (closed square), and with 160 μM P (closed triangle).
