摘　　要：分光光度法是测定人造板产品甲醛释放量最主要的定量方法。通过对乙酰丙酮法、酚试剂法和变色酸法等分光光度显色定量法的最佳检测线性范围、准确度、检出限、显色稳定性,以及不同方法之间的检测结果进行对比,为选择适宜的人造板产品甲醛释放量的定量方法提供依据。Spectrophotometry is one of the most common methods of quantitatively analyzing formaldehyde emissions from wood-based panel products. The comparative studies on the precision, limit, coloration stability and variability of formaldehyde concentration were conducted among acetylacetone method, MBTH Sawicki＇s reagent method and chromotropic acid method. The results provided a reference for selecting proper quantifying method for detecting formaldehyde emissions from wood-based panel products.
