Abstract:
Synthetic dyes have been in use for over a century and have been extensively applied across various industries, including leather, textiles, and pharmaceuticals. However, unlike natural dyes, synthetic dyes are less environmentally friendly due to their poor biodegradability, and some can even be harmful to the environment. Consequently, untreated wastewater from industries using synthetic dyes can lead to water pollution. Various methods exist for treating dye wastewater, with adsorption being particularly economical and effective, making it widely adopted. The efficiency of the adsorption process directly impacts the overall cost of wastewater treatment. Consequently, numerous studies have been conducted to enhance adsorption productivity. Analysts have utilized several kinetic models to investigate the adsorption mechanisms of dyes to identify ways to improve adsorption efficiency.
