The study explored the efficacy of an innovative adsorbent crafted from carbon nanotubes and nano fibbers integrated with aluminium oxide, in purging water solutions both organic (2-Nitrophenol) inorganic (Chromium III) contaminants. refined impregnation method to boost adsorption efficiency CNAs/Al2O3 removing certain pollutants. Through a central composite design (CCD) strategy, optimal conditions were determined. most effective removal 2-NPh Cr3+ occurred at 18% ratio, after 3 hours ultrasonication calcination Temperature 300 oC. This technique yielded capacities 82.02 mg/g for 96.57 Cr3+. content adsorbents, prepared under these specified conditions, was verified, measured using EDX (Energy Dispersive X-ray) analysis. Further, BET (Brunauer-Emmett-Teller) measurements revealed impact ratios on surface area CNAs/Al2O3, where 18 % ratio led 176 m2/g, diminishing 125 m2/g 110 20% 22% ratios, respectively. Predicted capacity estimated 83.154 mg/g, aligning closely observed while estimate 97.80 nearly matched actual mg/g. A validation evaluated predicted contaminants, finding that 86.79 99.79 noted acceptable error margin about 4.5% 2% optimized integration metal oxides CNAs through significantly enhances their pollutants, particularly when oxide is used purifying wastewater by extracting heavy
