The present invention relates to an adsorbent for lower aldehydes, which comprises a saturated cyclic secondary amine and a porous carrier therefor. The adsorbent can eliminate lower aldehydes efficiently at ordinary temperature over a long period and, furthermore, is inexpensive. And the adsorbent when a halogenide of an alkali metal or alkaline earth metal is further supported on the porous carrier, has an excellent heat resistance.
