|
Zeta potential can be estimated by using a zeta meter
|
|
True
|
|
|
False
|
|
|
Either A or B
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Zeta potential can be measured by dynamic light scattering (DLS) using a Zetasizer Nano ZS instrument (Malvern). One example of this process is to measure the zeta potential of Si nanocrystals.
Detailed explanation-2: -It does this by illuminating the particles with a laser and analysing the intensity fluctuations in the scattered light. If a small particle is illuminated by a light source such as a laser, the particle will scatter the light in all directions.
