Ash content and chemical elements in 10 clones of Hevea by scanning electron microscopy and energy dispersive spectroscopy SEM/EDS

Abstract

The process of generating energy through biomass is a viable alternative for the industrial sector. There are infinite materials that can be used in energy conversion. However, the generation of waste from conversion (ash) is one of drawbacks. Therefore, the objective of this study was to determine ash contents and identify semi quantitatively the main chemical elements in the wood ash progenies of 10 clones of rubber tree [Hevea brasiliensis (Willd. Ex Adr. De Juss.) Muell-Arg. by scanning electron microscopy and energy dispersive spectroscopy (SEM/EDS) analyses. Hevea brasiliensis presented low ash content, a favorable characteristic for energy conversion, being favorable in the conversion of biomass into energy. Thus, by ash analysis it possible to identify fundamental chemical elements that can be used in agriculture calcium, potassium, magnesium, and phosphorus. Including soil correction, and low levels of toxic elements, allowing new approaches of this product in the segment.
