A novel FeTiZn ternary oxide nanocomposite for spontaneous and efficient adsorptive removal of hexavalent chromium from polluted water.

ABSTRACT: This study investigates the adsorption performance of a FeTiZn oxide nanocomposite for the efficient removal of toxic hexavalent chromium [Cr(VI)] from aqueous media. The nanocomposite was synthesized via a simple aqueous co-precipitation route and characterized using XRD, FTIR, SEM, TEM, and EDX techniques, confirming its crystalline structure and uniform nanostructured morphology. Batch adsorption studies were conducted to evaluate the effects of pH, contact time, adsorbent dosage, and temperature on Cr(VI) removal. The maximum adsorption capacity (qmax) determined from the Langmuir model was 256.41 mg g⁻¹ at 298 K, indicating a high affinity toward Cr(VI) ions. Kinetic modeling revealed that adsorption followed a pseudo-second-order model (R² = 0.998), suggesting chemisorption as the ra
