In this investigation, a novel mesoporous silicate material (MS) was successfully synthesized from dolomite and applied for removal of hazardous dye Methylene Blue (MB). Properties of the material were characterized by XRD, FT-IR, BET, SEM-EDS, TEM, and TG-DSC. During the adsorption process, conditions like contact time, dye concentration, temperature and pH were studied to investigate the adsorption characteristics of the material. The adsorption capacity for MB could reach 111.65 mg/g. Thermodynamic and kinetic studies were also carried out in this paper. Moreover, a relative reasonable adsorption mechanism was revealed by XPS analysis. The results showed that the electronic induction between calcium and magnesium ions is advantageous to enhance the MB adsorption.
