In this work, the authors have successfully synthesised amorphous mesoporous magnesium silicate particles by the sol–gel technique combining with block copolymer P123 (EO20PO70EO20) as a template. Mesoporous magnesium silicate particles were characterised by X-ray diffraction, transmission electron microscopy, N2 adsorption–desorption technique, element mapping and energy-dispersive X-ray spectroscopy analysis. The results indicated that homogeneous amorphous mesoporous magnesium silicate particles have 298.4 m2/g of specific surface area and 5.5 nm of mesoporous channels. Using rhodamine B (RhoB) as a model dye, the adsorption capacity on mesoporous magnesium silicate particles can be estimated to 190 mg/g, and the regenerated particles also exhibited good adsorption performance. Therefore these mesoporous magnesium silicate particles have potential as adsorbents for the removal of dyes from water.
