Chromium exists from both natural geological processes and human actions, it has a substantial impact on health ecosystems. This study addresses the major challenges in using biochar as an environmentally friendly, sustainable, economical sorbent for removing chromium hexavalent throughout remediation process. The results exhibited that produced non-woody feedstocks pyrolyzed at (300°C −700°C) significantly large amount of various functional groups, higher pH (7 to 11.10) CEC (27 21.70 cmol kg−1), greater surface area (2–300 m2g−1), O/C H/C ratios with increasing carbonization temperature, adsorption capacities (1.63 435 mg g) superior performance removal compared biochars woody-biomass. use equilibrium isotherm, thermodynamic, kinetic models aids comprehending interactions between biochar, well their processes.

Nowadays, the use of natural absorbents to remove pollutants from POME has gained remarkable attention. The main objective this study is investigate suitability and performance modified peat soil as an adsorbent for removal NH3-N POME. chemical activation method was performed using readily available NaOH first time improve adsorption naturally low-cost soil. physical properties raw were determined water-holding capacity, moisture content, bulk density, porosity, BET surface area. adsorbents also characterized by SEM FTIR morphology composition. To optimize experimental parameters namely dosage, agitation rate, contact POME, response methodology (RSM) employed in with two different ratios. Substantial improvement attained after modification images showed a more porous space structure larger voids while FT-IR demonstrated distinctive functional groups At optimized conditions 5.71 g/L 50 rpm 38.96 min predicted efficiency been revealed 64.06 58.74 % at 1:20 1:30 ratios, respectively. investigation 69.12 ± 2.5 61.57 4.3 NH3-N. results good agreement. rapid (69.1 within 39 min) achieved chemically compared previously reported studies. Nevertheless, stability up three cycles reusability.
