Abstract
The research aimed to measure the trends of agricultural extension workers towards the application of A batch biosorption experiments were conducted to investigate and characterize some chemical properties of sawdust nanoparticles (nSD) that produced from mechanically milling and the bulk sawdust collected; to evaluate the potential of different woody sawdust nanoparticles for phosphate biosorption capacity; study the operating parameters including contact time, initial concentration, pH, temperature, dosage, size, competing ion, and the possible mechanisms responsible for phosphate removal from water by the high-sorptive biosorbent; to test the stability, regeneration and reusability of phosphate-loaded biosorbent; and to test the phosphate removal efficiency of the high-sorptive biosorbent on real agricultural wastewater. To achieve these objectives, series of experiments were conducted. Bougainvillea spectabilis (stem wood), Eucalyptus camaldulensis L. (wood-branch), and Psidium guaja L. (wood-branch) were collected from Alexandria, Egypt during pruning processes. Bark of the woody species was removed, and the wood was transferred to flakes or sawdust in a sawmill in Alexandria. Stock solution of 1000 mg/L PO4-3 or NH4+was prepared using KH2PO4 and NH4Cl salts. Different concentrations of phosphate/ammonium solutions were prepared freshly prior to its use. The woody-sawdust was oven-dried at approximately 50-60 ᵒC, and then mechanically ground by a RETSCH RMl00 electrical mortar grinder (Ball mill) to produce nanoscale sawdust particles (diminish the particle size to
