Abstract

Abstract The aim of this research was an investigation into creating a rigid gel application of benzotriazole (BTA), a complexing agent, as a new potential way of treating verdigris-damaged paper. Various gel recipes were mixed and tested on historical samples. The gel recipes varied in gellan gel concentration, BTA/solvent solution concentration, and BTA concentration. The recipe effectiveness was assessed using Hulthe’s indicator paper and MQuant™ Test Cu indicator strips, two types of indicator papers which detect free copper ions. The results showed that rigid gel application of BTA is effective in complexing the copper ions which may inhibit further damage to the paper caused by free copper ions. Some of the other effects of the gel were the simultaneous removal of paper discolouration by the gel. Further research is needed to refine the gel recipes as well as the treatment process to prevent or reduce potential tidelines and other possible negative side-effects of gel treatment.

凝胶、颜色和络合剂:苯并三唑在铜绿损坏纸上的刚性凝胶应用研究

摘要本研究的目的是研究将络合剂苯并三唑（BTA）作为一种新的潜在的治疗铜绿损坏纸张的方法，创造一种坚硬的凝胶应用。将各种凝胶配方混合并在历史样品上进行测试。凝胶配方在结冷凝胶浓度、BTA/溶剂溶液浓度和BTA浓度方面各不相同。使用Hulthe的指示纸和MQuant评估配方的有效性™ 测试Cu指示条，这是两种检测游离铜离子的指示纸。结果表明，BTA的刚性凝胶应用能有效地络合铜离子，从而抑制游离铜离子对纸张的进一步损伤。凝胶的其他一些效果是同时去除了凝胶引起的纸张变色。需要进一步的研究来完善凝胶配方和治疗过程，以预防或减少凝胶治疗的潜在潮差和其他可能的负面副作用。
