Amidst the increasing problems of water scarcity and textile pollution, wastewater treatment industry is in dire need affordable adsorbents. The needs to find cost-effective ways mitigate its environmental impact, as it a major cause pollution. Since stress globally, adsorbents are crucial for providing sustainable approachable solutions pollution problems, guaranteeing efficient treatment, encouraging preservation face growing concerns. purpose this study determine how well waste basalt quarry dust (BQD) works an adsorbent remove malachite green (MG) dye, cationic dye that source characterization BQD reveals zeta potential -23.3 mV, which promising indication MG adsorption. According BET analysis, surface area 8.731 m²/g, pore volume 0.015 cc/g, width 3.794 nm. Various kinetic equilibrium models used investigate adsorption process. kinetics show well-fitted pseudo-first-order non-linear model with adjusted R² value 0.99415. This shows effective reliable adsorbent. Sips isotherm excellent fit 0.9827, demonstrating robustness Thermodynamic studies emphasize spontaneity exothermic nature In addition these, response methodology optimising removal efficiency, quadratic central composite design process, exhibiting predicted 0.9917, greater than artificial neural network (R² = 0.9698). Desorption also demonstrate remarkable resilience adsorbent, maintaining 85% effectiveness after five cycles using 0.5 M HCl eluent. highlights long-term reuse BQD, supporting circular economy by advancing development processes environmentally friendly, utilizing byproducts from one resources treat another.
