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.

的凝胶,颜色和络合剂:苯并三唑在变色纸损坏的纸上硬质凝胶应用的研究

这项研究的目的是研究创建一种络合剂苯并三唑(BTA)的刚性凝胶应用,作为一种处理潜在的鲜铜绿纸的新方法。混合各种凝胶配方,并在历史样品上进行测试。凝胶配方的结冷胶浓度,BTA /溶剂溶液浓度和BTA浓度各不相同。使用Hulthe的试纸和MQuant™Test Cu试纸条(两种检测游离铜离子的试纸)评估了配方的有效性。结果表明,BTA的刚性凝胶法可有效地络合铜离子,这可能会抑制由游离铜离子对纸张造成的进一步损害。凝胶的其他一些作用是通过凝胶同时消除纸张变色。
