Crystal violet dye poses significant environmental and human health risks due to its toxicity, persistence, bioaccumulative nature. It contributes potential carcinogenicity, cytotoxicity, systemic toxicity upon exposure. To address this issue, a novel SrCO3/MgO/CaO/CaCO3 nanocomposite was synthesized using the Pechini sol-gel method, producing AE500 AE700 at 500 700 °C, respectively, for efficient removal of crystal from aqueous media. X-ray diffraction (XRD) analysis confirmed formation crystalline phases, with average crystallite sizes 64.53 nm 75.34 AE700. Energy-dispersive spectroscopy (EDX) revealed elemental compositions variations in carbon, oxygen, magnesium, calcium, strontium percentages influenced by synthesis temperature. Field-emission scanning electron microscopy (FE-SEM) showed morphological differences, where had irregular polyhedral structures, while exhibited more compact spherical formations, grain 99.98 132.23 nm, respectively. High-resolution transmission (HR-TEM) structural integrity nano-scale morphology, showing aggregated irregularly shaped particles AE500, displayed well-defined nearly nanoparticles. The calculated particle diameters were 21.67 41.19 AE700, demonstrating an increase size Adsorption studies demonstrated maximum capacities 230.41 mg/g 189.39 adsorption process exothermic, spontaneous, physical, following pseudo-first-order kinetic model Langmuir isotherm, indicating monolayer onto homogenous surface.
