Question

How to Separating noble gases by adsorption?

Answer 1

The mixture of noble gases obtained by the above method is separated into individual constituents by the use of coconut charcoal which adsorbs different gases at different temperatures.

The mixture of noble gases is passed into a double-walled bulb containing coconut charcoal and placed in a low-temperature bath at 173K. It is allowed to remain in contact with the charcoal for about half an hour. At 173K, only argon, krypton and xenon are adsorbed by the charcoal while helium and neon remain unadsorbed. These are pumped out and collected.

Answer 2

Answer:

Coconut charcoal

Explanation:

The gaseous mixture that is free of oxygen and nitrogen is used for separating the noble gases. This is done using coconut charcoal which adsorbs different gases at different temperatures.
