摘要：
Laboratory experiments with ammonia vapour on Vasa wood have been carried out to neutralize the acidity connected to the numerous outbreaks of acidic sulfate salts occurring on the wooden surfaces of the Swedish historical shipwreck Vasa (1628). The effects of the ammonia treatment have been evaluated by means of pH measurements, Fourier transform infrared (FUR) spectroscopy and size exclusion chromatography (SEC). The SEC analyses did not show any apparent effect on the cellulose in the polyethylene glycol-treated Vasa wood sample, while the FTIR results indicate sonic degradation of the holocellulose.
