Abstract
An international environmental issue is the infiltration of heavy metals into water systems. Typically, direct industrial discharge pollutes rivers, lakes, and ponds, and these pollutants can seep into groundwater systems through transport processes. Due to a sharp rise in heavy metals, the issues now require high attention. The purpose of this experiment is to look into how Cr6+ ions adsorb onto magnetite (Fe3O4)nanoparticles. Magnetic magnetite Fe3O4 nanoparticle synthesized by chemical co-precipitation was characterized using SEM-EDX, XRD, FTIR, zeta potential and sizer. The synthesized Fe3O4 nanoparticle was effective in removal of Cr6+ from water. The effect of temperature, pH, contact duration, and adsorbent dosage on Cr6+ adsorption was methodically examined in batch adsorption studies. At pH 2.0, the maximum amount of Cr6+ was removed. Thermodynamic analysis and adsorption data fit PSO kinetic, depicting the process's endothermic nature and spontaneity.The Temkin model best-describeCr6+ sorption on nanoparticle. Fe3O4 nanoparticle show potential as adsorbent for the removal of metal ions in wastewater and water treatment.
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...

Heavy metal contamination, particularly lead (Pb) pollution in aquatic environments, poses serious threats to ecosystems and human health, necessitating the development of efficient and cost-effective adsorbents. In this study, potassium permanganate-modified areca fiber biochar (PAFB) is successfully synthesized for P...
Water treatment plant (WTP) sludge was used as a low-cost adsorbent for manganese (Mn(II)) removal from aqueous solutions. The sludge was subjected to thermal treatment (80–500 °C) and chemical activation with KOH to enhance its physicochemical properties. The activated material exhibited increased porosity and surface...
