DETERMINATION OF IRON AND COPPER IN 18th AND 19th CENTURY BOOKS BY FLAMELESS ATOMIC ABSORPTION SPECTROSCOPY
Lucia C. Tang
ABSTRACT—Several badly foxed books and a paper handmade in our laboratory were studied for the presence and location of iron and copper compounds. The iron content of foxing spots and clear paper areas in the books showed a significant difference. However, the copper content of these areas was not significantly different. On the other hand, in our handmade paper it was the copper content that varied significantly in these areas. Traditionally, these elements in paper have been analyzed by gravimetric and titrimetric analytical techniques, colorimetry, or flame atomic absorption. CRA (Carbon Rod Atomizer), used with atomic absorption equipment, offers a simple, rapid and extremely sensitive method of determining metals in cellulosic materials directly on the solid sample.
