Crystal violet dye, widely used in industries, poses environmental and human health hazards due to its persistence toxicity. Effective removal methods are critical mitigate these impacts. This study presents the synthesis of a novel ZrO2@MnCO3@CdCO3 nanocomposite for efficient crystal dye from aqueous solutions. The was synthesized using precipitation method characterized XRD, SEM, EDX, BET surface area analysis. Adsorption experiments were conducted under various conditions, including pH, contact time, concentration, temperature. exhibited mesoporous structure (22.38 m2/g area, 0.0935 cm3/g total pore volume, 8.79 nm average size) an crystallite size 76.30 nm. maximum adsorption capacity 179.52 mg/g, following pseudo-second-order kinetics Langmuir isotherm. Thermodynamic studies revealed exothermic, physical, spontaneous process. Regeneration demonstrated high reusability with desorption efficiency reaching 99.67% over five cycles.
