The chemical properties of the paper determines its life; therefore, the durability of paper can be assessed by testing its chemical properties. Specimens of paper were individually treated by four oxidation decontamination materials, and then aged using dry heat. The paper samples were then characterized by measuring [alpha]-cellulose content, xylogen content, copper number and carboxylic acid content. These chemical properties were compared with those before aging, and with those of the blank paper samples. The results suggested that the chemical properties of the paper samples treated by KMnO4-H2C2O4 changed more than those treated by the other three materials. In contrast, the chemical properties of the paper samples treated by chloramine-T changed the least.
