Zeta potential measurements of CGAC, Zn[Cl.sub.2]-modified CGAC, and nitrate-loaded Zn[Cl.sub.2]-modified CGAC were carried out by the microelectrophoresis
(Malvern Zetasizer Nano ZS).
Investigations of hydrophobic/hydrophilic character and Lewis acid-base interactions were performed by using the microbial adhesion to solvents (MATS) method, and electrostatic properties were studied by microelectrophoresis
Laser Doppler Microelectrophoresis
was used to measure the velocity of mineral particles in the solution under an electric field.
The Doppler laser microelectrophoresis
technique with Zetasizer equipment (Nano-ZS Zetasizer[R] model ZEN 3600, Malvern, United Kingdom) was used to evaluate the zeta potential, expressing the results in millivolts.
To measure the zeta-potential of magnesite, dolomite, and quartz, experiments were carried out using the microelectrophoresis
is also used for the determination of IEP.
While DLS is used to measure particle size, the technique of laser doppler microelectrophoresis
is used for zeta potential measurement.
