摘要

环境监测对于博物馆、展厅和储藏室的天然材料的妥善保存至关重要。当由于污染、访客、非专业干预、不合适的储存条件、灾难或故意破坏而偏离中性pH条件时,就会发生天然材料的变质和降解。因此,测量博物馆大气中酸性或碱性气体含量的简单技术很重要,尤其是在物品长期放置的储藏室中。溶胶-凝胶pH传感器已被合成并应用于马德里国家自然博物馆(西班牙)的储藏室监测。在不同的气象季节进行了为期一年的pH监测。监测到的大多数储存系统保持中性pH,而其中一些是微酸性的。这些酸性条件可能有利于归化动物有机结构的化学退化,并导致物体矿物和无机部分的酸性腐蚀。

Application of pH sensors for preventive preservation in storerooms at the Museo Nacional de Ciencias Naturales (Madrid)
Environmental monitoring is essential for the proper preservation of natural materials in museums, both in exhibition halls and storerooms. Deterioration and degradation of natural materials occur when deviations from neutral pH conditions take place as a consequence of pollution, visitors, non-professional interventions, unsuitable storage conditions, catastrophes, or vandalism. Simple techniques to measure the extent of acidic or alkaline gasses in the museum atmosphere are therefore important, especially in storerooms where objects are placed for long periods. Sol-gel pH sensors have been synthesized and applied for monitoring storerooms of the Museo Nacional de Ciencias Naturales of Madrid (Spain). pH monitoring was carried out for one year under different meteorological seasons. Most of the storage systems monitored maintained a neutral pH, while some of them were slightly acidic. These acidic conditions could favour chemical deterioration on organic structures of naturalized animals, and cause acidic corrosion in minerals and inorganic parts of the objects.

期刊介绍: Conservar Património is a journal, published three times a year, that intends to create a space for the diffusion of conservator-restorers’ studies and activities. However, at a time when Conservation-Restoration pretends to develop further through collaboration with other areas of knowledge, such as History of Art, Archaeology, Museum Studies, Chemistry, Physics, Biology and other related disciplines from the fields of the natural and social sciences, the journal also receives contributions from any other provenance as long as directed towards the multiple dimensions of the works that integrate our Cultural Heritage. Theoretical issues on the conservation activity may also be submitted.
