Synchrotron-based sulfur X-ray absorption spectroscopy reveals considerable accumulation of organosulfur (e.g. thiols), pyrite and iron(II) sulfides in marine-archaeological wood preserved in seawater, e.g. for historical shipwrecks such as the Vasa and Mary Rose. In the museum, oxidation of the sulfur compounds in the presence of iron ions may cause severe acidity in the moist wood. This tutorial review discusses developments of conservation methods to remove acid and iron, and how to analyse and stabilise sulfur compounds in the wood.
基于同步加速器的硫X射线吸收光谱法揭示，保存在海水中的海洋考古木材（如瓦萨号和玛丽玫瑰号等历史沉船的木材）中大量积累了有机硫（如硫醇）、黄铁矿和硫化亚铁。在博物馆中，硫化合物在铁离子存在下的氧化可能会导致潮湿木材中产生严重的酸度。本教程综述讨论了去除酸和铁的保护方法的发展，以及如何分析和稳定木材中的硫化合物。
