Centrifuge is used to purify?

Explanation

Option A) A centrifuge relies on the principles of centripetal force accelerating molecules so that the particles of different masses are physically separated in a gradient along the radius of a rotating container. The prominent use of gas centrifuges is for the separation of uranium-235 (235U) from uranium-238 (238U).Option B) Hydrogen: Centrifugation is not typically used to purify hydrogen. Hydrogen is usually purified using other methods such as pressure swing adsorption (PSA) or membrane separation.Option C) Oxygen: Centrifugation is not typically used to purify oxygen. Oxygen is usually purified using other methods such as adsorption or cryogenic distillation.Option D) Nitrogen: Centrifugation is not typically used to purify nitrogen. Nitrogen is usually purified using other methods such as cryogenic distillation or membrane separation.
