This research applies to the regeneration rate and recycling capability of peanut shell magnetic biochar adsorbents capturing pollutants from water through IoT sensing microwave systems actuated by optimization algorithms. was done first crushing peanuts shells carbonizing them generate biochar, secondly adding Fe₃O₄ nanoparticles enhance adsorption surface ease which Richards can be separated mixture. Microwave-assisted also identified more efficient than conventional thermal methods, with yields up 88% achieving capacity in methylene blue dye Lead ions. Though smart sensors became monitor temperature other process order process. The application Machine learning model, Random Forest, on regression yielded a high R² score 0.91 for prediction allows feedback control system. proposed system increases regeneration, at same time it is less energy operating cost consuming comparison practices. present paper demonstrates that considered technologies successfully applied large scale both gases purifications wastewater treatment among most suitable areas. Future studies will attempt proving possibility use agricultural waste materials produce improved algorithms rejuvenation processes better models due machine learning. provides green, sustainable easily scalable method collecting or recovering biochar.

Heavy metals in water bodies are caused chiefly by anthropogenic activities: industrial wastes, agricultural runoff, mining and hazardous waste disposal further the causes. They could enter body through varied processes, including those direct contact with contaminated soils sediments, along atmospheric deposition. Recently, nanowaste biomass has been one of avenues for heavy metal removal from water. The following figures show that these nanoparticles prepared wastes can absorb ions. This adsorption involves complexation ions, which enhances binding; thus, be recovered using different desorption methods. innovative approach reduces concentrations to acceptable levels as required regulatory guidelines. It also provides a cost-effective environmentally benign alternative conventional remediation Various physical techniques then characterised obtained nano materials. crystal structure peanut shell (PS) its (PSNP) were described XRD, chemical composition was defined according Raman Spectroscopy FTIR. Present research identified biosorbent nanoparticle powder made shells 40 60 nm particle sizes, confirmed FESEM, HRTEM, BET Zeta analysis. PSNP efficiencies achieved Cu2+ Pb2+ 94% 91%, respectively. Contact time pH determine optimum conditions removing ions supplies.
