dc.description.abstractThis research involves phosphorus recovery from aqueous phase using sugarcane derived- nanobiochar. Nanobiochar was prepared from buk biochar using planetary ball mill and characterized for surface morphology (via scanning electron microscopy), mineralogy (X-ray diffraction studies), surface chemistry (Fourier-transform infrared spectroscopy). The results indicate that mechanochemical synthesis successfully produced nanobiochar with high surface area and enhanced porosity. P-adsorption process was investigated through batch experiments. The operational parameters, such as contact time, pH, and initial phosphorus concentration, are optimized to maximize phosphorus removal efficiency. The optimized pH and adsorbent dose 6.0 and 1gL-1, respectively at equilibrium time (7 min.). Kinetic (Pseudo-first-order and Pseudo-second-order) and isotherm models (Langmuir and Freundlich) were applied on experimental data. Pseudo-first-order and Langmuir model was best fitted in the experimental data. Nanobiochar was biocompatible for bacteria. The synthesized adsorbent may be used as a macronutrient nanofertilizer to enhance the growth and development of plants.
