Published online by Cambridge University Press: 15 December From the early days of radiocarbon dating, the standard sample treatment has involved removal of contamination from carbonates and humic acids by washes in acid and base, respectively.

A modification of this acid-base-acid ABA method has been suggested, especially for material older than 20, yr. However, the criticism of ABA and application of a more aggressive oxidizing method, such as wet oxidation ABOX or cellulose extraction, might only be needed in some special cases, for example, in the case of poorly preserved or chemically treated wood.

Evaluation of preparation methods in radiocarbon dating of old wood

Separation of cellulose seems to be the ultimate solution; however, it is not always applicable when samples contain small amounts of wood. Infrared spectra of treated samples and 14 C show that in most cases the ABA method is sufficient in removing the contamination of naturally deposited wood, even when the wood is of very old age.
