Abstract
We have examined the use of polyelectrolytes and charged block copolym ers as flocculants and stabilisers. The adsorbed layer was characteris ed by adsorption data and zeta-potential measurements. Furthermore, th e stability of Ludox dispersions in the presence of these polymers was investigated. We conclude that charged polymers can be used both as s tabilisers and flocculants. The in fluence that the polymers have depe nds critically on the polymer charge, the dosage and the molar mass of the polymers. In order to optimise their performance we formulate a n umber of requirements for the polymers.
