Industrial applications using improved measurements of particle surface charge
Total Grant Value
2004 - 2005
This project provides new information on particle surfaces in industrial liquors through zeta potential and acoustic measurements. A focus was the effect additives, and process conditions such as pH, temperature and ionic strength would have on the zeta potential.
A substantial proportion of the work was in refining the methods used to measure zeta potential in concentrated electrolyte systems, and identifying the strengths and limitations of the Dispersion Technology DT1200 instrument. The DT1200 electroacoustic spectrometer, the first instrument of its type in Australia, was assessed using both model systems and industrial samples.
