The methylene blue adsorption was carried out on a natural material powder of Acorus calamus treated firstly with H2SO4 and then activated by KMnO4. new called PACK. Fourier transform infrared (FT-IR) spectroscopy, pHpzc analysis, SEM micrograph were to characterize the material. Pseudo-first-order, pseudo-second-order pseudo-nth order constant rates calculated for analysis dynamics sorption pr...

Ethylene diaminetetraacetic acid (EDTA)-functionalized graphene was synthesized from Nigerian coal using a chemical exfoliation method and the applied for removal of Congo red dye aqueous solutions. The raw were characterized Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) scanning electron microscopy (SEM)–energy-dispersive (EDX) measurement pHpzc (pH point zero charge)...

In this study, activated carbons prepared from agrowastes by chemical activation were used to remove acetic acid an aqueous solution through a batch process. The adsorbents characterized SEM, XRD, FT-IR, and point of zero charge (pHpzc). effects adsorbent dosage, initial concentration, contact time considered. Equilibrium data was tested using Langmuir, Freundlich, Temkin, Frenkel–Halsey–Hill m...

Alginate-PEI beads are functionalized by phosphorylation and applied for the sorption of Nd(III) Mo(VI). The successful grafting phosphoryl groups (as tributyl phosphate derivative) is characterized FTIR XPS analysis, elemental titration (pHPZC), TGA, BET SEM-EDX analyses. multi-functional characteristics sorbent (i.e., carboxylic, hydroxyl, amine groups) contribute in binding metal ions having...

Globally, there is a rising demand for water purification. This driven by numerous factors, including economic growth, increasing population, shortage, and deterioration of quality. The current work highlights the manufacturing environmentally friendly highly efficient sorbent based on chitosan nanoparticles after successive crosslinking (using glutaraldehyde) modification through grafting 4-am...

The present review was carried out to analyze the works developed using adsorption technology remove anti-inflammatory ketoprofen (KET). main factors that inflated KET were analyzed. It found that, among adsorbents, those from ZnAl/biochar, algae-derived porous carbon, and powdered activated carbon highly efficient, reaching maximum capacities of 1081, 443, 362 mg g−1, respectively. capacity te...

A magnetic Schiff’s base chitosan-glutaraldehyde/Fe3O4 composite (CHT-GLA/ZnO/Fe3O4) was developed by incorporating zinc oxide (ZnO) nanoparticles into its structure to prepare an efficient adsorbent for the removal of remazol brilliant blue R (RBBR) dye. The CHT-GLA/ZnO/Fe3O4 characterized following methods: CHN, BET, FTIR, XRD, SEM–EDX, pHpzc, and potentiometric titrations. Box-Behnken design...

The present study focuses on the synthesis of Kaolin loaded Silver (Ag-KNC) and Nickel (Ni-KNC) nanocomposites by co-precipitation method. The surface morphology of them was determined by SEM technique while chemical composition was determined by FT-IR technique. The removal of Malachite Green Oxalate (MGO) was preceded by the adsorption method using (Ag-KNC) and (Ni-KNC). The adsorption mo...

Successive grafting of new sorbent bearing amino phosphonic groups based on chitosan nano magnetite particles was performed through successive coupling with formaldehyde. The produced composite characterized by the high sorption capacity toward rare earth elements (REEs) and consists different types functional (phosphonic, hydroxyls amine groups) that are used for enhancing properties. chemical...

Providing efficient and environmental friendly ways to recover lignocellulosic waste remains a challenge around the world. In this study, citric acid-catalyzed hydrothermal carbonization (CHTC) was coupled with pyrolysis convert date seed (Ds) into adsorbent material. regard, central composite design (CCD) using response surface methodology (RSM) developed examine influence of temperature, reac...
