本文采用X射线衍射仪、能量色散X射线荧光仪及离子色谱3种分析方法,对不同保存环境下铁质文物中的氯含量进行了检测分析。检测结果表明:含氯的腐蚀产物主要以β型羟基氧化铁—四方纤铁矿或可溶性氯化物的形式存在于铁锈中。本文的调查分析还表明,室外大气环境下保存的铁质文物平均氯含量最低,其次为近海出土的器物,海水打捞铁质文物平均氯含量最高,达到7mg/g以上。
In this paper, X-ray diffraction, energy dispersive X-ray fluorescence spectrometry and ion chromatography three kinds of analysis methods, the storage of iron in cultural relics in the content of chlorine were detected. The test results show that the corrosion products containing chlorine mainly exist in the rust in the form of β-type iron oxyhydroxide-tetragonite or soluble chloride. The investigation and analysis in this paper also show that the average content of chlorine in the iron cultural relic preserved in the outdoor atmosphere is the lowest, followed by the utensils unearthed in the offshore. The average content of chlorine in the iron relics salvaged by seawater is the highest, reaching above 7mg / g.
