摘　　要：该文研究出一种应用于铁器文物保护的脱氯清洗液。2%NaOH+0.1%十二烷基苯甲酸钠溶液+2%乙二胺+0.1%壬基酚聚氧乙烯醚(OP-10)+少量磷酸三钠清洗液的复配碱性脱氯清洗液效果最好。通过电化学实验可知,经复配碱性脱氯清洗液处理后的模拟铁器文物表面耐腐蚀性能有较大的改善。经复配碱性脱氯清洗液处理后的带锈试样红外吸收光谱证明其表面吸附有胺类物质,与铁离子反应生成配合物,有利于氯离子从腐蚀产物层迁出。The present paper makes a study of Desalination solution, and finds out that desalination in the ethylenediaminecontaining alkaline solution on rusted iron is more effective than traditional methods. The electrochemical behavior of the rusted iron after desalination has been examined by electrochemical impedance spectroscopy and potentiodynamic polarization. Surface composition of the treated rust sample has been characterized by infrared spectrum. The results show that a chelate membrane is induced on the surface of the treated rusted iron and the anti-orrosion performance is improved obviously.
