Abstract: Cellulose is the skeleton material of the wood cell wall, the content of cellulose is not only deciding the nature of the wood, but also an important quantitative indicator for wood’s modification in functional improvement of wood. The traditional method for determination of cellulose content has some disadvantages, such as long test time; taking much medicine, complex and so on. This paper based on the Fourier transform infrared spectrometry（FTIR’） to analyze the cellulose content of wood, then using potassium thiocyanate as internal standard to make several pieces of potassium bromide tablets containing different mass fraction of cellulose. Working curves were prepared by plotting the ratio of peak strength of cellulose to that of potassium thiocyanate（internal standard） versus content of cellulose. Measure the tablets that were composed of different wood’s powder, potassium thiocyanate and potassium bromide. According to the ratio of peak strength of cellulose and that of potassium thiocyanate, can get the percentage of mixture of cellulose from the working curves; also get the percentage of cellulose of wood. The experimental results show that the Fourier transform infrared spectrometry can realize rapid determination of cellulose content of wood.
