Abstract
A composite adsorbent comprising an acid salt of an m- or p-aromatic amino acid and an acid. The adsorbent may further contain a transition metal compound. The former removes aldehydes, ammonias and amines simultaneously, and the latter further removes hydrogen sulfide. The composite adsorbent is used in the form of a powder, a solution, or a solid supported on a carrier.
