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。

Abstract

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.
