dc.description.abstractToday, increasing dyes pollution is of great importance for life. Leaving the dyes used in industries such as textiles without being discharged pollutes other water sources. In order to prevent this, different methods are used in the literature. In this study, SrAl2B2O7, a borate metal, was used to remove methyl blue (MB), an anionic dye, by batch adsorption method. Strontium aluminoborate (SrAl2B2O7) was prepared using a solution combustion method at 950 degrees C for 4 h in air. The prepared adsorbent was characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The particle morphology of the adsorbent was investigated using scanning electron microscope (SEM). By using N-2 adsorption-desorption, the Brunnauer, Emmet, and Teller (BET) specific surface area was found to be 1.9578 m(2) g(-1). The surface charge of the dye-adsorbed SrAl2B2O7 was determined based on zeta-potential measurements. Langmuir (R-2=0.9897), Freundlich (R-2=0.985), Dubinin & Radushkevic (R-2=0.976), Scatchard (R-2=0.881), Temkin & Pyzhev (R-2=0.978) isotherms were calculated in the study. SrAl2B2O7 showed good adsorption performance for methyl blue (MB) with maximum adsorption capacities of 29.069 mg g(-1) (Langmuir). Adsorption processes were also studied in detail. Thermodynamic and kinetic models; pseudo-first-order (R-2=0.415), pseudo-second-order (R-2=0.999), Elovich (R-2=0.968) showed that adsorption using SrAl2B2O7 in MB removal is endothermic and pseudo-second order.en_US
