PURPOSE:To remove lower aldehydes rapidly and efficiently by preparing the removing agent by mixing with at least either aromatic amino acid or its salt as an effective component or by depositing the aforesaid effective component on a porous carrier. CONSTITUTION:A removing agent for lower aldehydes is prepared by mixing at least either aromatic amino acid or its salt as an effective component. In this embodiment, although the aromatic amino acid or its salt can be used in as-powdered state, in order to enhance its effect, it may be brought into an aqueous solution of optional concentration or the solution dissolved in an organic solvent or deposited on a porous carrier. Industrially, the aromatic amino acid, its salt and the porous carrier are mixed together by a mixer and pulverized by a crusher after drying for preparation of a powdery or granular removing agent. |
