AbstractHydrogen peroxide (HP) residues that remain after the conversion of blackened lead white may cause unwanted paper discolouration and degradation. Four VOCs sorption materials were tested for their ability to eliminate HP gas evolving from the treated substrate. This was tested by measuring the change in HP concentration in aqueous solution and in an enclosed air space in the presence of MicroChamber® Interleaving Paper, Corrosion Intercept® film, Zorflex® activated carbon cloth (ACC) and iron sulphate-impregnated paper. Detection with the colour indicator Quantofix® test strips and a Dräger X-am® 5100 single gas detection device showed that ACC is by far most efficient in decreasing the HP concentration. ACC was also effective in preventing paper discolouration in test objects that had been HP-treated for lead white conversion and then were stored sandwiched between ACC. Although ACC may not eliminate all HP from the substrate, it can diminish its negative effects on the treated object and protect other objects in the vicinity.

通过吸附剂消除铅白转化处理后的过氧化氢挥发物

摘要在黑铅白转化后残留的过氧化氢 (HP) 残留物可能会导致不必要的纸张变色和降解。测试了四种 VOC 吸附材料消除从处理过的基材中释放出的 HP 气体的能力。这是通过在存在 MicroChamber® Interleaving Paper、Corrosion Intercept® 薄膜、Zorflex® 活性炭布 (ACC) 和硫酸铁浸渍纸的情况下测量水溶液和封闭空气空间中 HP 浓度的变化来测试的。使用颜色指示剂 Quantofix® 试纸和 Dräger X-am® 5100 单一气体检测设备进行检测表明，ACC 在降低 HP 浓度方面是迄今为止最有效的。ACC 还可以有效防止测试对象的纸张变色，这些测试对象已经过 HP 处理以进行铅白转化，然后夹在 ACC 之间存储。尽管 ACC 可能无法消除基材上的所有 HP，但它可以减少其对处理对象的负面影响并保护附近的其他对象。
