Abstract: The present invention discloses a formaldehyde absorbent and a method for using the same, the chemical composition of the formaldehyde absorbent by weight percentage is, amino acid: 0.1-99.9%; DNA and RNA base 99.9-0.1%. The method comprises the following steps: a. dissolving the formaldehyde absorbent in solvent to form a solution or dissolving the formaldehyde absorbent in solvent and mixing the same onto a solid carrier; b. placing the solution or solid carrier in indoor space that contains formaldehyde; and c. contacting and reacting the formaldehyde-containing air with the solution or the solid carrier and then absorbing the same. The present invention not only achieves not only excellent performance in absorbing hazard gases in the air, but also features low-cost, and further causes no secondary pollution, which therefore creates great social and economical significance in improving quality of human life, safeguarding human health, and protecting environment.
