【摘要】：正脫鹽處理可以降低考古出土鐵器的氯離子濃度,提高文物的穩(wěn)定性。然而,對脫氯處理和鐵器腐蝕速率之間的關系,從未進行過定量的研究分析。英國卡迪夫大學考古與文物保護學院和大英博物館文物保護與科學研究部的研究人員選用英國3個不同考古遺址發(fā)掘出土的35根鐵釘,制作了66個樣品進行了實驗。在室溫條件(20±3)℃下,用0.1mol/L的氮氣脫氧NaOH溶液(dNaOH)或0.1mol/L NaOH/0.05mol/L Na2SO3溶液(AS20)對其中的35個樣品進行了脫氯處理,另外31個樣品未作處理。在75℃、75%RH的環(huán)
[Abstract]:The positive desalination treatment can reduce the chloride ion concentration of the excavated iron and improve the stability of the archaeological relics. However, the relationship between dechlorination and iron corrosion rate has never been quantitatively studied. Researchers from the College of Archaeology and Heritage Conservation of Cardiff University and the Department of Heritage Conservation and Scientific Research of the British Museum made 66 samples from 35 iron nails excavated from three different archaeological sites in Britain. At room temperature (20 鹵3) 鈩，
