红外光谱技术在制浆造纸工业的原料分析、 浆料检验及纸张检测等方面的应用已取得较大进展, 且发挥着重要的作用。 但传统的透射红外光谱在分析检测上存在破坏样品结构、 制样过程复杂、 测定时间较长等缺点, 已不能满足现代制浆造纸工业即时检测的需要。 为了实现待测样品的在线无损分析, 必须有一种快速而非破坏性的红外光谱技术予以辅助。 傅里叶变换衰减全反射红外光谱(ATR-FTIR)分析技术作为一项新的无损检测技术, 能够迅速、 准确地对制浆造纸各生产工段的产品进行全面无损评价, 目前已开始介入制浆造纸领域的相关科学研究中。 并较为详细地介绍了现阶段ATR-FTIR分析技术在制浆造纸工业各生产工段的研究与应用进展。

As one of the most powerful tools to investigate the compositions of raw materials and the property of pulp and paper, infrared spectroscopy has played an important role in pulp and paper industry. However, the traditional transmission infrared spectroscopy has not met the requirements of the producing processes because of its disadvantages of time consuming and sample destruction. New technique would be needed to be found. Fourier transform attenuated total reflection infrared spectroscopy (ATR-FTIR) is an advanced spectroscopic tool for nondestructive evaluation and could rapidly, accurately estimate the production properties of each process in pulp and paper industry. The present review describes the application of ATR-FTIR in analysis of pulp and paper industry. The analysis processes will include: pulping, papermaking, environmental protecting, special processing and paper identifying.
