摘要
新旧版GB/T17657中干燥器法采用的乙酰丙酮溶液配制方法存在差异。本实验通过分析乙酰丙酮溶液储存时间影响标准工作曲线的规律,侧面反映其对甲醛释放量检测的影响。实验结果显示,按GB/T17657-2022制备的乙酰丙酮溶液,在14d内对甲醛的检测影响不大,且适合使用10mm光程的比色皿。
Preparation methods of acetylacetone solution using in the desiccator method between the new and old version GB/T17657 are differences.In this experiment,influence of detecting formaldehyde emission is reflected through the storage time of acetylacetone solution how to affect the standard working curve.The experimental results show that acetylacetone solution preparated from GB/T17657-2022,in 14 days,has little influence on the detection of formaldehyde,and is suitable to use a cuvette with 10mm optical path.
