FIG. 14.

Zeta potentials and electrophoretic mobility of different compounds versus pH: hydrocarbon oil droplets (a), sulphonated polystyrene latex (b), arabic acid as carboxylated polymer (c), and serum albumin (d). Note that there are polymers (b), typically containing periodically arranged heavily charged, phosphorylated or sulphonated groups along their chains,^[103] possessing linear and flat ζ potential versus pH curves.
