Measuring particle surface charge and particle interactions in process liquors
Total Grant Value
This 3 year project used the DT1200 instrument to measure zeta potential for solids in caustic solutions up to 10m NaOH.
It showed that rheology is capable of reflecting changes in zeta potential of dispersions in concentrated caustic liquors, and that colour of a red mud slurry can be used to determine its relative degree of flocculation, among numerous other results.
