“…In previous studies, the Corsel model (Corsel et al, 1986) was employed to model the kinetics of the competitive adsorption of metal cations (Teodoro et al, 2017) and cationic dyes (Fideles et al, 2019) The kinetic parameters estimated by the Corsel et al (1986) are presented in Table 5.…”

<p>The batch adsorption technique investigated the efficiency of sawdust adsorbent for removing copper ions from synthetic solutions. A chemical synthesis process prepared the activated sawdust powder, and its surface area and pore volume were obtained by BET isotherm analysis. The ability of copper ion uptake by activated sawdust powder was examined under the characterization study of SEM, EDX & FTIR studies. Various isotherm studies checked the process of adsorption, and the kinetic studies confirm the nature of the adsorption process with sawdust adsorbent. Thermodynamic studies were used to analyze the endothermic nature of the adsorption process, and 0.3 N of H2SO4 acid desorbs 93.27% of copper ions from the spent adsorbent. The experimental study confirms the better adsorption ability of sawdust powder in the activated charcoal form to remove the heavy metal pollution in aqueous solutions.</p>

“…Among these, the adsorption process seems to be the most promising removal pathways of this contaminant [16,17]. Because of the large amount produced, being non-toxic and low cost, agricultural residues such as fruit [18,19], sawdust [20], rice husks [21], coconut fibers [22,23] and sugarcane bagasse [24][25][26], show as an alternative to this adsorption process.…”

Chemical treatment of sugarcane bagasse and its influence on glyphosate adsorption

Due to the production rates of sugarcane, nowadays, the sugarcane bagasse stemming in the sugar and alcohol industry is the agro-industrial waste produced in greater volume throughout in Brazil. In 2019, about 192 million tons of this waste were generated. The use of this waste has been the aim of researches around the world, with emphasis on applications that aim to meet the prerogatives of the concept of circular economy. Within this scenario, sugarcane bagasse (SB) was treated in an alkaline medium, forming an adsorbent material, SBNaOH. The effects of chemical treatment were evaluated for surface properties and for glyphosate removal in an aqueous medium. The adsorptive phenomenon was studied through isotherm tests. The results obtained were fitted to classical models of Langmuir, Freundlich and Dubinin-Radushkevich. The characterization indicated that the chemical treatment promoted an important change in the surface of the residue, increasing the surface area. SB and SBNAOH had a feasible behavior as adsorbent and good performance in the removal of the herbicide, presenting values greater than 65% of under all working conditions. The theoretical adsorption saturation governed by Dubinin-Radushkevich (qS) was in the order of 8.988 mg/g (R2=0.988) for SB at 120 minutes of contact and maximum adsorption capacity by Langmuir (Qmax) was 13.720 mg/g (R2=0.984) for SBNaOH at 40 minutes of contact. The process was governed by the exchange or sharing of electrons. The adsorbate is distributed heterogeneously on the SB surface, justifying the presence of active sites with greater ionic strength, and homogeneously on the SBNaOH surface (monolayer). In general, the treated sugarcane bagasse, coming from an agro-industrial residue, proved to be an alternative and promising biosorbent for the removal of glyphosate from aqueous systems, thus generating a new application of this residue.
