Which of the following is the most suitable for extraction in a system having very low density difference ?
Correct answer: D. Centrifugal extractor
- A. Mixer-settler extractor
- B. Packed extraction tower
- C. Pulsed extractor
- D. Centrifugal extractor
Explanation
A centrifugal extractor generates a strong artificial gravitational field, allowing rapid phase separation even when the density difference between the two liquids is very small. Mixer-settlers and packed towers rely more heavily on natural settling and are less suitable in this case.
