Efficient adsorptive removal of Congo Red dye using activated carbon derived from Spathodea campanulata flowers

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 13, 2025

Abstract This report investigates the preparation, characterization, and application of activated carbon derived from Spathodea campanulata flowers (SCAC) to remove Congo Red (CR) dye aqueous streams. SCAC was synthesized using orthophosphoric acid activation which yielded a mesoporous material with specific surface area (986.41 m 2 /g), significantly exceeding values reported for flower-derived carbons in available literature. Field emission scanning electron microscopy (FESEM) image revealed an irregular, rough morphology pre-adsorption, became smoother post-adsorption, indicating successful CR attachment. Elemental analysis through energy-dispersive x-ray spectroscopy (EDS) X-ray photoelectron (XPS) confirmed increase content appearance sulfur, verifying uptake. Adsorption kinetics obeyed pseudo-second-order equation, signifying chemisorption, while equilibrium dataset fitted better Langmuir model, R 0.9944, suggesting monolayer adsorption mechanism maximum capacity 59.27 mg/g. Thermodynamic spontaneous endothermic process. Desorption studies showed methanol as most effective desorbing agent, retaining considerable across six cycles, highlighting its reusability. In tests real water matrices, demonstrated higher removal efficiency natural waters than control, enhanced complex matrices. These findings underscore practical applicability real-world wastewater treatment, offering promising solution large-scale industrial applications.

Sustainable Approaches for Pharmaceutical Pollutant Removal: Advances in Chitosan‐Based Nanocomposite Adsorbents

ChemistrySelect, Journal Year: 2025, Volume and Issue: 10(13)

Published: April 1, 2025

Abstract The growing presence of pharmaceutical pollutants in aquatic environments poses significant threats to both human health and ecosystems. Despite their crucial role healthcare, pharmaceuticals enter water systems through various sources, making them some the most critical environmental contaminants. Traditional wastewater treatments, which are classified into physical, chemical, biological techniques, often struggle effectively remove pharmaceuticals. Among these methods, adsorption stands out as a reliable versatile approach for removing organic enhancing efficiency treatment processes. Biopolymers, particularly chitosan, gaining attention due numerous advantages, including biocompatibility, biodegradability, affordability, high capability, non‐toxicity, availability from diverse natural sources. Chitosan, hydrophilic biopolymer, can be chemically modified by incorporating nanoparticles (e.g., metal oxides, carbon‐based materials, magnetic particles) boost its efficiency. These advancements enable chitosan‐based nanocomposites range pharmaceuticals, antibiotics, analgesics, hormones, water. This review examines latest developments nanocomposite adsorbents, emphasizing fundamental mechanisms, optimization conditions, kinetic behaviors, isotherm models. factors collectively determine capturing pollutants. Moreover, underscores potential materials remediation, offering valuable insights application future research directions. Ultimately, aim this is provide insight offer an innovative effective solution challenge contamination By addressing key challenges utilizing advanced material designs, adsorbents hold great promise sustainable efficient removal systems.
