介绍了近红外漫反射技术在纸浆卡伯值定量分析测定中的应用。用近红外光谱仪对竹浆、蔗渣浆、松木浆样品的卡伯值进行了分析测定。研究结果表明,用近红外方法对纸浆卡伯值的测定是可行和有效的,样品不需预处理,分析快速、简便、环保,结果准确。
The application of near infrared diffuse reflectance technique in the quantitative analysis of kappa number of pulp was introduced. The kappa number of bamboo pulp, bagasse pulp and pine wood pulp was analyzed by near infrared spectroscopy. The results show that the Kappa number of the pulp is feasible and effective by near-infrared spectrometry. The sample need not be pre-treated, and the analysis is fast, simple, environmental-friendly and the result is accurate.
