Abstract:
Abstract: Nanofabrication of phosphorus on kaolin mineral receptacles refers to the fabrication of nanomaterial by
The present stripper has been designed to mechanize pod separation of pigeonpea with high labour intercalating phosphate ion (PO₄³⁻) on kaolin clay mineral for its slow and consistent release in the soils
efficiency, timeliness in completion of operation and also economizing the operation. The separated pods when applied as fertilizer. It relates to the dissolution of phosphate ion in rhizospheric acid medium from
can be efficiently threshed by pod thresher with minor adjustment in operational parameters. Combination phosphorous rich mineral species. Here, PO₄³⁻ was brought to solution phase from Pcontaining mineral
of spike tooth type and wire loop type elements attains maximum stripping efficiency without damaging fractions and transported to reaction chamber, where they were intercalated in the kaolin clay mineral
the seed and stalk. The optimum rotation speed for stripping cylinder is about 9.6 m/s. The material of spike moiety. P containing mineral fractions was free from heavy metals and other contaminants, and thereby
tooth plays an important role in minimizing mechanical injury to seed during stripping. The nylon spikes final nanoproduct was free from those. It was hypothesized that when the final nanoproduct is applied to
embedded with tempered steel is found effective in reducing minor injury to seed as well as exhibited soil as fertilizer, it would release either of PO₄³⁻ , or get converted to hydrogen phosphate ion (HPO₄²⁻ )
toughness towards bending or breakage of spikes. Overall, the stripper is able to reduce labour requirement or dihydrogen phosphate ion (H₂PO₄- ), due to presence of water in soil. The final product was dried and
by 80 % and reduction in cost of operation by 73 % with 7 percent point enhanced recovery. stored in sterilized container.
