MAGNETICALLY MODIFIED SUGARCANE BAGASSE BIOCHAR AS CADMIUM REMOVAL AGENT IN WATER

Heavy metals are hazardous to health at certain levels. Currently, heavy removed by physicochemical treatments, such as adsorption, flotation, and electrochemical deposition, also biological algal biofilm reactor anaerobic ammonium oxidation. In this study, magnetic biochar was produced enhance the effectiveness performance of adsorbent for metal removal. This study aimed synthesise high-performance biochar, determine optimum parameters conditions high yield removal cadmium (Cd2+) from aqueous solution, adsorption kinetics isotherms Cd2+ Nickel oxide (NiO)-impregnated sugarcane bagasse subjected slow pyrolysis produce biochar. The impregnated metal, temperature, time were varied solution batch conducted. synthesised characterised using field-emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX), diffraction (XRD), Brunauer-Emmett-Teller (BET) surface area, Fourier transform infrared (FTIR), vibrating sample magnetometer (VSM). data agreed well with pseudo-second-order model followed Langmuir isotherm model. achieved 88.47% efficiency solution. Thus, a human carcinogen reduces effects on toxicity in environment. ABSTRAK: Logam berat adalah berbahaya bagi kesihatan di peringkat tertentu. Pada masa ini, logam disingkirkan melalui rawatan fizikokimia, seperti penyerapan, pengapungan, dan deposit elektrokimia, biologikal, reaktor biofilem alga oksidasi anerobik. Kajian ini menghasilkan magnetik meningkatkan keberkesanan prestasi penyerapan penyingkiran berat. bertujuan mengsintesis pada tinggi, parameter keadaan pengeluaran tinggi kadmium daripada larutan akues, mendapatkan kinetik isoterma Cd2+. Nikel oksida (NiO)-impregnat hampas tebu berdasarkan pirolisis perlahan magnetik. yang terimpregnat, suhu tempoh dipelbagaikan berprestasi-tinggi. Penyingkiran akues kajian berkumpulan telah dibuat. Biochar disentisis diklasifikasikan menggunakan mikroskopi elektron imbasan medan-pancaran tenaga sebaran pembelauan kawasan permukaan (BET), Penjelmaan inframerah sampel getaran Data menunjukkan persetujuan dengan aturan-kedua-pseudo mengikuti Langmuir. mencapai akues. Oleh itu, sebagai karsinogen manusia mengurangkan kesan teruk pengurangan toksik alam sekitar.
