Abstract

Abstract

Using NaOH,HCl,and NaCl as pretreatment reagents,under different solution concentrations (0.1%,1%,4%,8%),the main chemical components of bamboo before and after treatment were analyzed. The changes in the chemical composition and morphology of the bamboo before and after chemical pretreatment were characterized by Fourier transform infrared-attenuated total reflectance spectroscopy (FTIR-ATR),X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) to obtain the main change and mechanism. Furthermore, the influence of chemical pretreatment on the growth of TiO₂ nanoparticles on the bamboo surface was investigated. The results showed that after 10 min treatments, compared with original bamboo,HCl and NaCl-treated bamboo,the characteristic peaks of NaOH-treated bamboo at 1 730 cm^-1 and 1 238 cm^-1 were changed significantly, decreasing gradually with the increase of NaOH solution concentration. According to the XPS results,the hydroxyl (-OH) on the bamboo surface can be completely replaced by Na ions after 4% NaOH treatment. Increasing the concentration to 8% will not continue to increase the Na content. In addition,the SEM and XPS results indicated that the NaOH pretreatment can promote the loading of TiO₂ nanoparticles on the bamboo surface.
