摘要
介绍了采用紫外分光光度法测定酚醛胶合板中游离苯酚含量的步骤。该方法是通过水蒸气蒸馏法提取苯酚，然后采用紫外可见分光光度法测定苯酚含量。结果表明，在波长269．70nm处、苯酚浓度在0-160μg／mL范围内吸光度与苯酚浓度呈线性关系，这为胶合板中游离苯酚含量的测定提供了新的方法。
The steps for measuring the content of free phenol in the amberwood with the UV spectrophotometry method are introduced. In this method, phenol is extracted with a steam distillation method, after which the UV spectrophotometry is used to determine the content of phenol. The result shows that there is a linear relationship between phenol concentration and absorbance in the case of 269.70-nanometer wave length and 0-160 μ g/mL phenol concentration, which provides a new method for determination of the content of free phenol in the plywood.
