Adsorptive Removal of Pb(II), Ni(II), and Co(II) from Simulated Wastewater Using Delonix Regia Seed: Equilibrium and Kinetic Studies

The development of low-cost biosorbents from agricultural biomass offers a sustainable approach for the remediation of heavy metal-contaminated wastewater. In this study, Delonix regia seed (DRS) was evaluated as a natural biosorbent for the removal of Pb(II), Ni(II), and Co(II) ions from simulated wastewater. The ad...

Hydroxyapatite-loaded coal gasification slag for synergistic heavy metal adsorption

Summary Lead-zinc mining wastewater contains Pb(II), Cu(II), and Cd(II) that are difficult to remove efficiently. A coal gasification slag-supported nano-hydroxyapatite composite (nHAP-CGS) was prepared via chemical precipitation. The composite achieved removal efficiencies of 97.6%, 94.9%, and 79.8% for Pb(II), Cu(II)...

Adsorption of Heavy Metal Ions [Cr(VI), Fe(III) And Zn(II)] on Chemically Activated Murraya Koenigii(Curry Leaf) Biosorbent

The present study investigates the potential of chemically activated Murrayakoenigii biosorbent (CAMKB) for the efficient removal of Cr (VI), Fe (III), and Zn (II) ions from aqueous solutions. The biosorbent was prepared from waste curry leaves through phosphoric acid activation followed by thermal treatment. Batch ads...

Enhanced Pb(II) and Co(II) Removal Using Magnesium-Enriched Bismuth Ferrite Composites with Bentonite and Opuntia-Derived Carbon: Kinetics, Isotherms, and Thermodynamic Analysis

Recoverable Fe3O4@SiO2@TMC magnetic sorbent for efficient Congo red removal: performance and adsorption mechanism

The increasing discharge of dye-laden wastewater necessitates the development of efficient and easily recoverable adsorbents. In this study, a trimesoyl chloride (TMC) functionalized Fe3O4@SiO2 magnetic sorbent was synthesized via a sol–gel route for the removal of Congo red (CR) from aqueous media. Dynamic light scatt...

Facile Synthesis of Magnetic ZIF-67@Fe3O4 Composite with Synergistic Properties for Monolayer Adsorption of Pb(II) Pollutants

The development of efficient and easily recoverable adsorbents for heavy metal removal remains a significant challenge in wastewater treatment. In this study, a magnetic ZIF-67@Fe3O4 (ZIFO) composite was successfully synthesized via a simple methanol-assisted in situ method at ambient temperature for the removal of Pb(...
