    摘要: 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.

    摘要: A method for using a polymer-carbon sorbent for removing one or more of carbon dioxide, heavy metals or toxic materials from a flue gas from coal-fired power plants is described. The sorbent comprises a carbonaceous sorbent material and a cured amine-containing polymer, and sulfur. The polymer-carbon sorbents are formed by curing a curable amine-containing polymer in the presence of the carbonaceous sorbent material, sulfur, a cure accelerator and, optionally, a cure activator. A convenient carbonaceous sorbent material is an activated carbon, and a convenient curable amine-containing polymer is an allyl-containing poly(ethyleneimine), having a number average molecular weight between about 1,000 and about 10,000. The polymer-carbon sorbents may contain sulfur in molar excess of an amount needed to cure the curable amine-containing polymer. Such polymer-carbon sorbents are shown to capture more mercury, in both elemental an ionic forms, compared to activated carbon and adsorb carbon dioxide.
