摘要
为研究AMT复合剂在去除青铜文物粉状锈和氯离子的作用,用AMT复合剂与CuCl进行化学反应,并将反应后的絮状物进行EDS、IR和XRD分析,原始反应液及清洗絮状物最后一次所得洗液中Cl-采用离子色谱法(IC)分析;原始反应液中的阳离子采用电感耦合等离子光谱直读仪(ICP)分析。分析结果表明:AMT复合剂与CuCl反应生成的絮状物与清洗青铜文物过程中析出的絮状物形貌相同,说明AMT复合剂可能渗入到青铜文物锈层并与锈层内的CuCl充分反应,提取出Cl-。
In order to study the effect of AMT composite in removing Cl^- and bronze antique＇ s powder rest, the reactive process of AMT composite reagent with CuCl^- was tested. After treatment, the cottony substance was analyzed by energy dispersion spectrometer, infrared spectroscopy and X - ray diffraction, Cl^- content of original reactive liquid and last lotion was analyzed by ion chromatography, the cation of original reactive liquid was analyzed by inductively coupled plasma. The results indicate that the Cottony substance of AMT composite reagent reacting with CuCl is the same as the Cottony substance produced by cleaning bronze with AMT composite reagent, and AMT composite reagent could penetrate inside bronze and could react sufficiently with CuCl, finally could clean out Cl^-.
