High concentrations of iron in groundwater pose serious health risks. To address this challenge, a magnetic nanocomposite material was synthesised by incorporating magnetic nanoparticles and multi-wall carbon nanotubes into a chitosan and sodium alginate matrix. Thorough physicochemical analyses verified the structural and thermal characteristics of the material. Performance tests examined the effects of retention time, sorbent dosage, initial iron concentration, pH, agitation rate, and temperature on iron removal. The adsorption behaviour corresponded closely with the Langmuir isotherm model, achieving a maximum monolayer capacity of 12.43 milligrams per gram, and adhered to pseudo-second-order kinetics. Thermodynamic evaluations confirmed that the uptake of iron ions is spontaneous and endothermic. These findings demonstrate that the composite offers viable adsorption capabilities for water treatment and purification applications.
Elevated iron levels in groundwater present substantial health hazards to communities relying on untreated sources. Developing effective, functional adsorbents provides a means of extracting harmful metal ions from drinking supplies. By demonstrating stable, spontaneous iron uptake under various operational conditions, this work points towards cleaner drinking water and safer municipal or community water management.
The material could enable targeted iron extraction for water treatment facilities, environmental remediation services, and water purification equipment providers. Tested at laboratory scale across varied pH, temperature, and dosing parameters, the technology remains early-stage research. Transitioning towards commercial use would require validation in natural groundwater streams alongside testing for reusability, scalable synthesis, and integration into existing filtration or magnetic separation infrastructure.

The widespread presence of iron pollution in groundwater is a major global worry, as increased levels can lead to severe health hazards. To tackle this urgent problem, we engaged in a synthesis procedure where magnetic nanoparticles (MNPs) and multi-wall carbon nanotubes (CNTs) were combined with a mixture of chitosan (CS) and sodium alginate (Alg) to produce a magnetic composite material. This novel composite, known as CS/Alg/MNPs/CNTs, was crafted with the primary aim of effectively removing iron from groundwater through adsorption. A thorough physicochemical analysis using FTIR, SEM, PSA, XRD, DSC, and TGA confirmed the composition's characteristics. The study delved into the influence of parameters such as retention time, sorbent dose, initial Fe concentration, pH, agitation rate, and temperature on the adsorption process. The Langmuir isotherm model fittingly represented the adsorption data, indicating a monolayer coverage of 12.43 mg/g and aligning with the pseudo-second-order kinetic model. Additionally, the adsorption of iron ions by the composite material was identified as a endothermic process. Furthermore, the study highlights the sorption process's inherent spontaneity and survivability, as demonstrated by the negative ΔG value. In conclusion, the results of this study indicate that the magnetic composite adsorbent (CS/Alg/MNPs/CNTs) holds considerable promise for effectively removing iron ions from groundwater, making it a viable and attractive choice for use in water purification applications.
