Abstract

Abstract Hydrogen 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.

通过吸附剂去除铅白转化处理后的过氧化氢挥发物

摘要黑化铅白转化后残留的过氧化氢（HP）残留物可能会导致纸张变色和降解。测试了四种挥发性有机物吸附材料消除处理后基质中HP气体的能力。在MicroChamber®交织纸、Corrosion Intercept®薄膜、Zorflex®活性炭布（ACC）和硫酸铁浸渍纸存在的情况下，通过测量水溶液和封闭空气空间中HP浓度的变化来进行测试。用彩色指示剂Quantofix®测试条和Dräger X-am®5100单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也能有效防止经过HP处理的铅白色转换测试对象的纸张变色，然后将其夹在ACC之间储存。虽然ACC可能无法消除基底中的所有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。
