Investigation of Efficient Adsorption of Toxic Heavy Metals (Chromium, Lead, Cadmium) from Aquatic Environment Using Orange Peel Cellulose as Adsorbent

Heavy metals in the environment cause adverse effects on living organisms. Agro-wastes have potential to remove heavy from aqueous solutions. In this study, orange peel cellulose (OPC) beads were utilized as adsorbents wastewater. The surface of adsorbent was studied by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy coupled with energy dispersive x-ray (SEM-EDS). concentrations before after adsorption measured using inductively plasma mass spectrometry. removal metal ions (i.e., Cr6+, Cd2+, Pb2+) OPC investigated varying pH, contact time, dosages parameters. maximum efficiency obtained for occurred at pHs 4–8. use Langmuir isotherm Freundlich models demonstrated statistical significance processes (R2 > 0.96). At a neutral order Pb2+ Cd2+ Cr6+ % values 98.33, 93.91, 33.50, respectively. equilibrium reached 36 h. For Pb2+, 8 12 h, FT-IR SEM-EDS confirmed presence many functional groups elements adsorbent. is low-cost, eco-friendly, innovative method aquatic environments. findings study will be highly significant public affected areas worldwide that credible health concerns due water contamination metals.
