Particle Polarity


Determination of particle polarity of bituminous emulsions

The test consists in passing a direct or rectified electric current through a bitumen emulsion placed between two parallel plate electrodes.

The deposition of a layer of bitumen on the anode indicates a negative charge: the emulsion is therefore anionic.

The deposition of a layer of bitumen on the cathode indicates a positive charge: the emulsion is therefore cationic.
