摘要
Abstract
Based on GB 18583-2008"Indoor decorating and refuibishing materials-Limit of harmful substances of adhesives",the free formaldehyde content in adhesives was determined by acetylacetone method.In order to improve accuracy of determination results for free-formaldehyde content in adhesives,we explore the factors which may have an effect on determination results of free-formaldehyde.The experimental results showed that the results obtained were more accurate when the distillation time was controlled at 90 min,the solution was filtered before color development,and the storage time was controlled within 40 min after color development.关键词
