The contamination of aquatic environments with hexavalent chromium (Cr(VI)) poses significant environmental and public health risks, necessitating the development high-performance adsorbents for its efficient removal. This study evaluates potential green-synthesized nanoscale zero-valent iron-modified sludge biochar (TP-nZVI/BC) as an effective adsorbent Cr(VI) removal through isothermal adsorption experiments, fixed-bed column studies, artificial neural network (ANN) modeling. Fixed-bed experiments demonstrated that breakthrough time, exhaustion unit capacity increased bed height. Conversely, these parameters decreased higher influent concentrations flow rates. Breakthrough curve analysis revealed Thomas model provided best fit experimental data (R2 = 0.992–0.998). An ANN model, developed using Levenberg–Marquardt algorithm, employed a single hidden layer six neurons exhibited excellent predictive performance 0.996, MSE 0.520). was validated ability to predict behavior under untested conditions, demonstrating applicability process optimization. highlights superior TP-nZVI/BC establishes theoretical basis optimizing scaling up systems findings provide valuable insights into practical application sustainable materials in remediation.
