Abstract: Hassan, A. Z. A., Mahmoud, A. W. M., Turky, G. M. & Safwat, G. (2020). Rice husk derived biochar as smart ma-terial loading nano nutrients and microorganisms. Bulg.
Present exploration aspired to produce biochar from rice husk basic nano particles using slow pyrolysis technique. The physio-chemical characteristics, phases and surface morphology of biochar were studied by different visual techniques.
The obtained result confirmed that rice husk derive biochar is considered as a novel carrier of nano nutrients and advanta-geous microorganisms. The recorded values of mean radius, nearest distance between particles, perimeter of particles, the sur-face area of biochar basic nano particles, cation and anion exchange capacity were examined. The image of surface topography showed that biochar enrich by nano-particles with “sponge” shaped structures and nano-particles were imbedded into macro, meso, and micro pores of biochar. The spacemen atoms of pure elements composition of biochar followed the descending order of oxygen > silicon > sodium > potassium > carbon > magnesium > calcium > alumina. The stability and fertility of biochar basic nano particles might be used as safety soil amendment, climate changes mitigation, source of fertilizer and eco-friendly. The determined conductivity of the prepared biochar is found in the range of semiconductors which make it suitable and prom-ising material to be used as filler in polymer composites and nano composites for many electric and electronic applications.
