Insights into Phosphate Adsorption Performance onto Magnetic Thermal Modified Palygorskite Nanocomposites

Eutrophication caused by excessive discharging of phosphorus is a global water pollution problem. To further improve the adsorption capacity natural palygorskite and easy separation from liquid, magnetic thermal modified nanocomposite (MTPG) was firstly fabricated then characterized XRD SEM-EDS. The characterization results showed Fe3O4 in nano-diameters prosperously immobilized on surface (TPG) calcinated at temperature 700 °C. Abundant nano-scale loading almost doubled specific area (SSA) TPG. phosphate onto MTPG highly pH-dependent slightly influenced ionic strength. According to Langmuir model, maximum adsorptive quantity 400.00 mg/g counted 298 K. regeneration ratio 80.98% after three cycles. process confirmed be an endothermic spontaneous chemisorption. Thus, cost-effective, excellent affinity, great recovery performance, high had enormous promising utilization removal aqueous solutions.
