“…1b. The diffraction pattern depicted by STpe clearly conforms to the amorphous nature of lignocellulosic materials 33,64 . However, crystalline peaks were displayed in the diffraction patterns exhibited by STpe-AgNP attributed to the impregnation of the silver nanoparticles (AgNPs) onto the biosorbent.…”

“…2a,b. The SEM image of pure STpe displayed a slightly rough surface morphology without particle distribution 33 . However, after impregnation www.nature.com/scientificreports/ with silver, STpe-AgNP showed increased surface roughness, due to the AgNPs distributed on the hybrid adsorbent surface.…”

“…The FTIR spectrum of pristine STpe showed a broad OH band at 3291 cm −133 . The C-H stretching of alkenes and alkanes was observed by IR absorption bands at 2923 cm −1 , while the C≡C group corresponded to IR absorption bands at 2199 and 2049 cm −129, 33 . Absorption at 1638 cm −1 was attributed to carbonyl C=O stretching, with the C=C band of alkenes observed at 1374 cm −133, 53 .…”

“…Absorption at 1638 cm −1 was attributed to carbonyl C=O stretching, with the C=C band of alkenes observed at 1374 cm −133, 53 . The absorption bands at 1154 cm −1 and 1003 cm −1 were due to the C-O stretching vibration 33,59 . After impregnation of AgNP onto the STpe adsorbent forming the hybrid (STpe-AgNP), slight shifts in the IR absorption bands from 2923 to 2917 cm −1 , 2199 to 2193 cm −1 , 2049 to 2021 cm −1 , 1638 to 1623 cm −1 , 1374 to 1389 cm −1 and 1003 to 998 cm −1 frequencies, suggested interactions of the corresponding functional groups on STpe with the attached AgNPs.…”

This work was aimed at the synthesis of a hybrid (STpe-AgNP), obtained by impregnation of silver nanoparticles (AgNP) onto Solanum tuberosum peel (STpe), for the ultrasonic assisted adsorption of bromophenol blue (BB) dye. SEM, FTIR, XRD, EDX, TGA and BET techniques were used to characterize the adsorbents. The XRD, SEM and EDX confirmed successful impregnation of AgNPs onto STpe to form the hybrid. The AgNPs impregnated onto the hybrid were found to be water stable at various pH values of 2.0–9.0. Chi-square (χ2 < 0.024) and linear regression (R2 > 0.996) showed that the Freundlich model was best fitted among the isotherm models, corroborated by the oriented site model. Kinetic analysis conformed to the intraparticle diffusion and pseudo-first-order rate equations, while thermodynamics displayed a physical, spontaneous and endothermic adsorption process. The presence of competing Pb(II), Ni(II), Cd(II) and Zn(II) metal ions in solution interfered with the adsorption of BB onto the biosorbents. In terms of reusability, STpe and STpe-AgNP showed BB desorption of 91.3% and 88.5% respectively, using NaOH as eluent. Ultra-sonication significantly enhanced the adsorption of BB by both adsorbents, but the impregnation of AgNPs only slightly improved adsorption of the dye from the simulated wastewater. This study also illustrated that pristine STpe biomass waste is a cheap viable option for the decontamination of BB from water.

This study presents the adsorption process of methylene blue and other organic pigments in water samples using synthetic materials derived from agricultural waste combined with Fe3O4. The properties of the materials were determined through Fourier transform infrared spectroscopy, scanning electron microscopy, X‐ray diffraction, and nitrogen adsorption‐desorption isotherm. The result shows the successful association of Fe3O4 on materials prepared from agriculture with a surface area = 3.594 m2 g−1 and a pore size of 49.713 nm. The optimal factors of methylene blue removal process, such as pH, mass, initial concentration, time, and shaking speed, were also investigated, respectively. The maximum adsorption capacity of the material is 268.64 mg g−1, with an adsorption efficiency of 98.84%. The research method was applied to analyze and evaluate the materials' adsorption capacity in the southern provinces of Vietnam water samples.
