Abstract：The novel mesoporous silica MBT-MCM-41 was prepared by hydrothermal synthesis method, in which hexadecyl trimethyl ammonium bromide, tetraethyl orthosilicate and 2-mercaptobenzothiazole (MBT) were used as template, silicon source and modification agent, respectively. The mesoporous materials were analyzed and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and fourier transform infrared spectrometer (FT-IR). The material not only possesses regular morphology, and also has highly ordered crystal structure and porous. Its crystal distance is about 4.7 nm. When the material was utilized to treat the standard solution containing 30 mg/L lead ions at the pH of 5 and adsorption equilibrium was obtained after 20 min, the removal rate was better than 97.80%. Using the material to handle lead sewage, the removal rate was higher than 99.0% and the residual concentration was lower than the national standard.
