_______________ extractor is used for the concentration of radioactive nuclear waste?
Correct answer: B. Pulsed column
- A. Sieve plate
- B. Pulsed column
- C. Mixer-settler
- D. Bollman
Explanation
A pulsed column enhances mixing and mass transfer through repeated pulsations, making it suitable for liquid-liquid extraction of radioactive nuclear waste. Mixer-settlers are also extractors, but pulsed columns are the standard choice identified here.
