Removal of amoxicillin in aqueous solutions by a chemical activated carbons derived from Jujube nuts: adsorption behaviors, kinetic and thermodynamic studies

Pb(II) Ion Removal Potential in Chemically Modified Ziziphus joazeiro Barks

“…Therefore, the classification and good adjustments of this models point to probable chemical adsorption. As the Langmuir equation obtained the smallest error functions and better fit, this scenery suggests that the surfaces of the samples are energetically homogeneous with monolayer adsorption on a surface containing a finite number of identical sites [ 41 , 77 ].…”

“…The lignocellulosic raw materials have good specific surface area and the presence of functional organic groups and mineral content that allow interaction with various pollutants, from toxic metals to dyes and organic compounds [ 23 , 35 , 37 , 38 , 39 , 40 , 41 , 42 ]. The bark of Ziziphus joazeiro , in addition to presenting the adsorptive advantages of plant material, also has the presence of the functional groups of the structures of the saponins, which may be active sites for interaction with pollutants.…”

Preparation of Granular Activated Carbon Particle Electrode Loaded with Co3O4 and its Effect on Amoxicillin Wastewater Treatment

“…A strong absorption peak at a wavelength of 228 nm and a weak absorption peak at a wavelength of 272 nm were observed, which correspond to the π-π* transition and the n-π* transition of the benzene ring in the AMX structure, respectively. 54,55 However, these peaks rapidly weakened with the increase of the treatment time, and completely disappeared after 40 min of treatment. At various treatment times, however, additional weak peaks were produced at wavelengths of 244 nm and 347 nm, which were then gradually enhanced or decreased.…”
