“…As a result, the chemical reaction between the RO16 dye and C-TPP-PEE was the rate-limiting step in the dye adsorption process. Similar results were obtained in the biosorption of Congo Red from an aqueous solution using cabbage waste powder [36] and Reactive Red 120 adsorption from aqueous solutions by a polyaniline-Scenedesmus biocomposite [37]. Also, k 2 is used to describe the rate of adsorption equilibrium.…”

The green composite chitosan/tripolyphosphate/mushroom (C-TPP-PEE) was synthesized and evaluated for its adsorption performance of the dye Reactive Orange 16 (RO16), by using the batch technique. Fourier-transform infrared spectroscopy, thermogravimetric analysis, and field emission scanning electron microscopy were employed to characterize the C-TPP-PEE. The maximum adsorption capacity of the RO16 dye for batch adsorption was determined as 736 mg g -1 . The experimental kinetic data at equilibrium was found to be best fitted to the pseudo-second-order kinetic model. The results showed that the adsorption isotherm was best correlated to the Langmuir model. The thermodynamic data indicated that the adsorption process was spontaneous, favorable, and endothermic.

This work reports the adsorptive removal of congo red using as-fabricated polyvinylidene fluoride (PVDF) membranes modified with beta cyclodextrin (β-CD). Diverse techniques were used to characterize the membranes' performance and microstructural and morphological properties. The effect of pH, dye initial concentration, adsorbent dosage, contact time on adsorption efficiency were investigated. Filtration studies were carried out using a deadend cell. The results showed that the introduction of β-CD in membrane matrix improved membrane performance, adsorption, and filtration properties.Bulk porosity increased from 61.46% to 87.55% and contact angle decreased from 84.17 0 to 67.93 0 . Water flux at 1 bar improved from 12.42 to 269.08 L.m À2 . hr À1 . Maximum adsorption for congo red was obtained at pH 7, with PVDF/β-CD membranes removing 96.15% and pristine PVDF removing 54.27% of congo red. The adsorptive removal of congo red was best described by the pseudosecond order kinetics and best fitted the Freundlich isotherm model. According

“…Adsorption processes are considered relatively simple methods, effective in the removal of various pollutants in aqueous solution or industrial wastewater treatment [12]. For the removal of some organic pollutants, different adsorbent materials have been used for the elimination of organic pollutants in the aqueous phase, such as bentonite, chitosan [13], composites [14] and biochars [15]. This last material has been of great interest due to its high porosity and adsorption capacity [6], therefore, the objective of this research is to synthesize a biochar with and without Ce-Fe nanoparticles for the adsorption of AMP in the aqueous phase from the use of the peel from the Punica granatum.…”

This research presents the obtaining of a biochar (CB) from the use of pomegranate peel (Punica granatum) conditioned with iron and cerium nanoparticles (C-Fe/Ce), as well as its characterization by SEM (Scanning Electronic Microscopy), FTIR (Fourier Transform Infrared Spectrometry), TGA (Thermogravimetric analysis), EDS (Energy Dispersive Spectroscopy), XPS (X-Ray Photoelectron Spectroscopy) and evaluation of the adsorption capacity of ampicillin (AMP) in aqueous phase at 20, 30 and 40 C. The maximum adsorption capacity for CB was 18.97 mg g À1 and for C-Fe/Ce, 27.61 mg g À1 at pH of 7, observing that with increasing temperature, the sorption capacity decreases in both materials, the experimental data was fitted to various mathematical models and the best fit was the pseudo-second order model for the kinetics, whilst for the adsorption isotherms the best fit was with the Langmuir model, indicating that the adsorption process is carried out in a monolayer on a homogeneous surface, through a chemisorption process. According to the thermodynamic parameters this process is carried out through an exothermic reaction. The results obtained indicate that both materials are suitable for the removal of AMP in the aqueous phase and that they can be reused up to 5 times.
