The template method's synthesis of SBA-15 material with spherical particles is performed using a surfactant Pluronic P123 (non-ionic triblock copolymer, EO20PO70O20 under acidic conditions. Instead of a commercial cosurfactant, a spent HCl solution obtained after chemical treatment of clay purification was provided with synthesis conditions to form spherical SBA-15. Obtained spherical particles have had diameters ranging up to 2 μm. The spherical shape of the particles and their silicate origin was confirmed by SEM and EDS methods, respectively. In addition to the methods mentioned above, XRD, FTIR and the particle size distributed method was also used to characterize the surface characteristic of spherical SBA-15.
