Hypothesis
This study aims to develop efficient and sustainable hydrogels for dye adsorption, addressing the critical need for improved wastewater treatment methods.
Conclusion
The study successfully synthesized CMC-based hydrogels that demonstrated a maximum adsorption capacity of 681 mg/g for methylene blue dye.
Supporting Evidence
- The optimal hydrogel was obtained at a radiation dose of 5 kGy.
- The 5:7.5 hydrogel achieved the highest swelling ratio of 18774.60 (g/g).
- FTIR spectroscopy confirmed the successful formation of the hydrogel.
- DSC analysis showed that higher AAc content increased thermal stability.
- The maximum adsorption capacity for methylene blue was 681 mg/g.
Takeaway
The researchers made special gels that can soak up harmful dye from water, helping to clean it better and more sustainably.
Methodology
Gamma radiation polymerization was used to synthesize CMC-based hydrogels grafted with acrylic acid, followed by various tests to evaluate their properties and dye adsorption capacity.
Limitations
The study did not address the optimization of hydrogels for complex industrial wastewater containing multiple contaminants.
