New Organomineral Complex from Humic Substances Extracted from Poultry Wastes: Synthesis, Characterization and Controlled Release Study

“…The band γ is attributed to the aliphatic groups of lateral chains, while the band G is attributed to the aromatic groups with ordering similar to those of the graphite plan (002). 22 This study was successfully employed by some authors 13,20,23,26 that reinforced the results of such technique.…”

“…Since the sand is basically composed of SiO 2 , the fine peaks found in the X-ray diffractogram may be related to the referred oxide. 24,25 However, since it is a macromolecule that may vary the composition and that still does not have a completely defined crystalline structure, the literature 26 reports studies involving the aromaticity based on the percentage occupied by the bands γ and G for the interpretation of X-ray diffractogram. The band γ is attributed to the aliphatic groups of lateral chains, while the band G is attributed to the aromatic groups with ordering similar to those of the graphite plan (002).…”
