Abstract
POLYELECTROLYTES are increasingly being used as flocculants for electrostatically stabilised dispersions of colloidal particles in such diverse fields as water treatment and mineral processing1. Suitable polyelectrolytes, which are usually effective at low concentrations (≤10 p.p.m.), invariably have a high molecular weight2 (a viscosity average molecular weight MV>105). They seem to function by a bridging mechanism whereby the flocculant interferes with the free movement of the particles1–6.
