In this study, potassium aluminum borate (K2Al2B2O7) was synthesized and investigated as an adsorbent for the removal of Alizarin Yellow GG (AYGG), an environmentally hazardous and water-soluble azo dye. The synthesized material was characterized using FT-IR, XRD, and SEM–EDS analyses, which revealed its crystalline structure and surface morphology. Batch adsorption experiments were conducted to investigate the effects of pH, adsorbent dosage, contact time, temperature, and initial dye concentration. Under optimized conditions, adsorption was favored at low pH and moderate adsorbent dosage. Kinetic analysis demonstrated that the pseudo-second-order model best described the adsorption behavior, while the Langmuir isotherm provided the most suitable fit, yielding a maximum adsorption capacity of 40.98 mg/g. Thermodynamic parameters indicated that the adsorption process was endothermic and spontaneous. The obtained data were modeled using artificial neural networks (ANN), which exhibited a high predictive performance (R2 = 0.9947) and showed strong agreement with the experimental results. Overall, the findings demonstrate that K₂Al₂B₂O₇ is a cost-effective and efficient adsorbent for the removal of textile dyes from aqueous solutions.
