Description
Water pollution due to synthetic dyes from textile, pharmaceutical, and other industries poses a serious environmental challenge. Conventional treatment methods, such as chemical coagulation and biological degradation, often fall short due to inefficiency and secondary pollution. This study explores the potential of cold plasma technology for the efficient removal of dyes from contaminated water. Cold plasma, a non-thermal ionized gas, generates reactive species such as hydroxyl radicals (•OH), ozone (O₃), and hydrogen peroxide (H₂O₂), which degrade complex dye molecules into harmless byproducts.
The research investigates the efficiency of cold plasma in degrading commonly used dyes such as methylene blue and reactive black 5 under varying operational conditions, including plasma exposure time, gas composition, and initial dye concentration. Experimental results indicate that cold plasma achieves high degradation rates, surpassing 90% removal efficiency within a short treatment duration. Additionally, toxicity analysis confirms that plasma-treated water is significantly less harmful compared to untreated samples.
The findings highlight cold plasma as an eco-friendly and effective alternative to conventional dye removal techniques. Its ability to operate at ambient temperatures without the need for additional chemicals makes it a promising solution for sustainable wastewater treatment. Further optimization and scale-up studies are recommended to enhance its industrial applicability.
