Organic silicon waste residue was used as silicon source to prepare MCM-41 mesoporous silica by using alkali fusion and hydrothermal reaction method. The effect of alkali fusion time and liquid-solid ratio on extraction rate of the silicon source was evaluated, while the effect of CTAB/SiO2 molar ratio on structure of the mesoporous silica was detailly explored. Besides, adsorption performance of the MCM-41 toward Rhodamine B (RhB) was comprehensively studied. It was found that the MCM-41 possessed highest degree of ordered mesoporous structure, after calcining for 2 h, with the liquid-solid ratio of 50∶1 mL/g, and CTAB/SiO2 molar ratio of 1∶0.3. Accordingly, the specific surface area, pore size and pore volume of the sample were 783.23 m2/g, 2.529 nm and 0.7479 cm3/g, respectively. In addition, the RhB could be effectively removed with MCM-41, with the maximum efficiency to be 295.23 mg/g. Isotherm and kinetic studies revealed that the RhB removal process could be well fitted with Langmuir and pseudo-second-order kinetic models. Meanwhile, owing to its spontaneous and exothermic adsorption, MCM-41 exhibited a high recyclability.
