“…A great advantage of this process is the wide variety of materials that can be employed as adsorbents, including agricultural wastes from different origins, geomaterials, and minerals. In order to improve the contaminants' adsorption capacity, different approaches to physical or chemical modifications have been applied to these materials, such as acidic, basic, thermal, or steam activation [14]. Regarding MET wastewater removal through plant-based adsorbents, there are reports in the literature of the use of Moringa oleifera seed husks functionalized with iron oxide nanoparticles [15], activated carbon from Zea mays tassels [16], orange peel [17], and chichá-do-cerrado (Sterculia striata St. Hil.…”

The present study investigated the use of a biosorbent produced from Leucaena leucocephala pods for the removal of metformin from aqueous solutions. The pods were subjected to chemical and thermal treatments and were referred to as L. leucocephala modified, which was characterized using scanning electron microscopy (SEM). The parameters investigated in the sorption process were temperature, contact time, adsorbent dosage, pH, and initial metformin concentration. The experimental data were in accordance with the Langmuir isothermal model. The maximum adsorption capacity reached was 56.18 mg g−1 at 313 K. In the kinetic study, stability was achieved in 300 min, with 53.24% removal, and the pseudo-first-order model agreed well with the experimental data. The thermodynamic parameters indicated a spontaneous, favorable, and exothermic reaction. The presence of NaCl, CaCl2, and MgCl2 negatively affected metformin adsorption. Thus, the importance of the study was that a developed material showed promising results in the removal of metformin, particularly because it is an innovative material, and there are no studies in the literature on drug removal using L. leucocephala.

A new synthesis of polyvinyl chloride (PVC-grafted-4-amicacid phenol, which consist of a reaction between poly (vinyl chloride ) and 4-amic acid phenol . Grafting structure has been checked by, FTIR, 1HNMR, 13C NMR, TG, DSC and X-RAY .The grafting of PVC work to changes the surface properties such as catalytic ability, adhesion and adsorption capacity. This paper describes grafting of polyvinyl chloride (PVC) as adsorbent for pb+2 ions removal. The adsorption process recorded comparatively rapid uptake of pb+2 by the new PVC-grafted-4-amicacid phenol which was mainly complexation controlled.

BACKGROUNDDeveloping robust technologies to remove emerging pollutants from water is urgent since conventional treatments are not technically prepared to remove them. This paper investigated the ibuprofen (IBU) adsorption capacity onto natural zeolite (NZ) and hydrothermally modified zeolite in an acidic medium followed by impregnation with the cationic surfactant cetyltrimethylammonium bromide (CTAB) (MZHT‐CTAB). The materials characterization included scanning electron microscopy (SEM), X‐ray diffraction (XRD), atomic absorption spectroscopy (AAS), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA/DTG), N2 adsorption/desorption isotherm (BET), Zeta Potential (ZP), and Point of Zero Charge (pHPZC). The adsorptive capacity studies were carried out by varying the pH solution, a kinetic study at three concentrations (25, 50, and 100 mg L−1), and the contaminant concentration influence (5–100 mg L−1).RESULTSThe results showed that the MZHT‐CTAB obtained both the highest removal efficiency (~ 37%) and the highest adsorption capacity (~ 14 mg g−1) at pH 5.0. The Pseudo Second‐Order (PSO) model, which showed the best fit to the experimental data, is significant as it indicates the reliability of our results. The maximum adsorption capacity for the concentration of 100 mg L−1 was 11.93 mg g−1. According to Giles's classification, the isotherm was classified as S‐3 type, indicating the competition between the adsorbate and water molecules for the active sites on the adsorbent surface.CONCLUSIONThe adsorption studies demonstrate that the novel adsorbent (MZHT‐CTAB) is highly effective in removing IBU, presenting a significant removal capacity and feasibility. This promising result contributes to the ongoing search for alternative materials for water treatment. © 2024 Society of Chemical Industry (SCI).
