“…Zeolites are microporous crystalline aluminosilicate structures and provide selective molecular trapping based on size and polar properties (Dyer 1988). Other molecular traps include activated carbon and synthetic, acid-resistant zeolites, which are cast into the paper matrix containing alkaline buffers (Passaglia 1987;Guttman and Jewet 1993). Molecular traps have been used for preventing and slowing down degradation and have been successfully used for paper materials, books, and photographs.…”

Embrittlement threatens the useful lifetime of books, maps, manuscripts, and works of art on paper during storage, circulation, and display in libraries, museums, and archives. Past studies have traced much of the embrittlement to the Brønsted-acidic conditions under which printing papers have been made, especially during the period between the mid-1800s to about 1990. This article reviews measures that conservators and collection managers have taken to reduce the acidity of books and other paper-based materials, thereby decreasing the rates of acidcatalyzed hydrolysis and other changes leading to embrittlement. Technical challenges include the selection of an alkaline additive, selecting and implementing a way to distribute this alkaline substance uniformly in the sheet and bound volumes, avoiding excessively high pH conditions, minimizing the rate of loss of physical properties such as resistance to folding, and avoiding any conditions that cause evident damage to the documents one is trying to preserve. Developers have achieved considerable progress, and modern librarians and researchers have many procedures from which to choose as a starting point for further developments.

“…High performance liquid chromatography (HPLC) on aqueous extracts showed eight peaks from the newsprint aged with SO 2 , and six peaks in the absence of SO 2 . Of the eight components found in newsprint aged in SO 2 , six were tentatively identified as 2 -ketoglutaric acid, malic acid, malonic acid, succinic acid, formic acid, and acetic acid. In the absence of SO 2 , four acids were tentatively identified (malonic, succinic, formic and acetic acids).…”

This report describes experiments in the accelerated aging of paper under static environmental conditions.The experiments were designed to measure effects of a relatively high pollutant concentration of 2500 ppm SO 2 at a slightly elevated temperature and humidity (air at 60°C and 25 percent relative humidity) .These conditions may simulate long term effects of this common air pollutant usually found in ambient concentrations between 0.1 and 2.0 ppm.
