Sugarcane Bagasse-, Orange Peel-Derived Adsorbent Materials: Thermal and Morphological Studies

Abstract

In this work, agro-industrial wastes such as sugarcane bagasse and orange peel were used for obtaining activated carbons through phosphoric acid activation in order to propose them as adsorbent materials during the production of carbon foam or filters for wastewater treatment applications. A two-step process was carry out to obtain activated carbons; the first step consisted of a simple physical activation at high temperature 400 °C to reach raw material decomposition; followed by acid activation at temperature of 500 °C. The effect of concentration of acid media (45, 65 and 85 wt.%) was analyzed in terms of the thermal stability, sorption, textural and structural properties. Surface area increases with the concentration of activation media, which is ranging from 114.08–355.52 m2 g−1, 49.54–228.90 m2 g−1 for sugarcane bagasse and orange peel, respectively. Fourier transform-infrared spectra showed the presence of functional C–O–P group, which confirmed with the thermal stability of the samples. The produced carbon foams showed a two-level cell structure with bubble and bar-like structures that increase the pore quantity in the carbon foams.

Data that support the use of agro-industrial residues from orange peel and sugarcane bagasse for the production of carbonaceous structures and their application in the removal of metal ions

“…Activated carbons were prepared from two agro-industrial wastes: orange peel (OP) and sugarcane bagasse (SCB), which were donated by Ingenio Pánuco S.A.P.I de C.V., and the OP was collected from the waste of a natural fruit juice. Initially, the samples were cleaned with distilled water and dried at 80 °C for 12 h. Subsequently, the raw materials were activated following the method previously reported [6] , biomass degradation was carried out through the pyrolysis process under the following conditions: temperature at 400 °C under inert atmosphere (argon gas). In general, pyrolysis showed higher ash content, higher surface area development due to the loss of carbon components at high temperatures, and higher micropore volume, respectively [4] .…”

Lignocellulosic Materials for the Production of Biofuels, Biochemicals and Biomaterials and Applications of Lignocellulose-Based Polyurethanes: A Review

“…Likewise, banana peel- and palm-flower-waste-based derived products were also able to remove methylene blue and malachite green dyes from polluted solutions [ 100 , 101 ]. Other studies obtained proper adsorbents from residual products such as orange peel and sugarcane bagasse [ 102 ]. A detailed review of this matter has been recently published [ 103 ].…”
