“…The change in the format of the diffractograms (Fig. 6) was confirmed by the refinement data; it was possible to note that the amount of quartz phase increased in all activated carbons synthesized from ashes, especially the A.C. (IV) in which its composition was 100% quartz; this is relevant data that showed that this material can be used as a source of crystalline SiO 2 in various processes from catalyst synthesis, molecular sieves, and zeolites, in addition to being used in energy applications and civil construction [65][66][67][68].…”

Nanostructured crystalline composite (activated carbon) was synthesized from residual ashes of the burning process of the sludge generated in the flotation step of a poultry slaughterhouse and was used for Allura red dye adsorption. The ashes were chemically activated using two types of reagents, H 2 O 2 and H 3 PO 4 , and the structure, morphology, and surface of the adsorbents were characterized by different techniques such as scanning electron microscopy with energy dispersive spectroscopy (SEM/ EDS), N 2 adsorption/desorption isotherms with Brunauer-Emmett-Teller (BET) method and Barret-Joyner-Hallenda (BJH) method, Fourier transform infrared spectroscopy (MID/FTIR), X-ray diffraction (XRD), and the point of zero charge (PZC). The adsorbent synthesized with H 3 PO 4 at 400 ºC displayed the best performance in removing dye molecules in 10 mg.L -1 solution, with a removal rate of approximately 100% when using a concentration of 2 g.L -1 in particle size of 0.42 mm. Besides that, the adsorbent synthesized with H 3 PO 4 had a particle diameter of approximately 15 Å, a size corresponding to the nanometer range, presented a crystallinity structure with well-defined phases such as quartz and the major elements in the composition were carbon and silicon. The surface area of the ashes enlarged from 14.71 to 448.1 m 2 .g -1 when H 3 PO 4 was used as an activator, producing a high-quality adsorbent, with an excellent cost-benefit, being it possible to be produced for a price of 9.35 USD.kg -1 , a price lower than the commercial activated carbon, making it a promising candidate for application in an industrial environment.

“…Sugarcane bagasse is frequently used as fuel in combustion systems generating new solid waste, mainly two types of ashes: the sugarcane bagasse bottom ashes (SBBA) and the sugarcane bagasse fly ashes (SBFA). Some researchers have analyzed the use of SBFA in civil engineering [11][12][13][14]. However, finding other recycling processes to give value to this waste is of great interest.…”

The sugarcane bagasse fly ash was used to evaluate its adsorption behavior for phenol removal from aqueous solution at three different temperatures. Adsorption tests were performed in batch reactors and also in fixed-bed columns. Pseudo-first order, pseudosecond order and intraparticle diffusion kinetic models were applied to describe adsorption kinetics in batch systems. The pseudo-second model fitted appropriately the obtained experimental data at the three different temperatures tested. Thomas, Yoon-Nelson, Adams-Bohart and Dose-Response mathematical models were tested for describing phenol adsorption in dynamic systems (fixed bed columns). Experimental data were well-fitted to the non-linear form of all these models with high regression coefficients.

“…Such ashes have been promoted as complementary raw materials for asphalt technologies, hydrogen production, hydraulic cement, ceramic building materials, and water remediation (Alavi-Borazjani et al, 2019;Brooks et al, 2019;Molin Filho et al, 2019;Tosti et al, 2019). Furthermore, several studies have demonstrated that different types of ashes have the outstanding absorption capacities for various pollutants present in wastewater, such as organic dyes, pesticides, phenols, toxic metals, and numerous other inorganic contaminants (Johansson et al, 2016;Khodadadi et al, 2019;Yadav et al, 2014).…”
