Synthesis and Application of Eco-Friendly Adsorbent for Treatment of Congo Red and KMnO4 Dye Aqueous Solution

Abstract

The use of natural resources as environmentally acceptable adsorbents for wastewater treatment was investigated in two research. The first concentrated on using bamboo leaves as an inexpensive adsorbent to remove the dye KMnO4. Bamboo leaves were carefully synthesised, spectrophotometrically analysed, and showed different adsorption capabilities according to unit adsorbent concentration. The second study used a systematic synthesis procedure and spectrophotometric characterization to remove Congo red dye from mango leaves. The Mangifera indica adsorbent demonstrated a noteworthy 88.27% adsorption peak at a dye concentration of 50 mg/L. Both programmes emphasised the potential of renewable resources and focused on low-cost, environmentally friendly methods to address the problem of water contamination. The research emphasised the adaptability and effectiveness of natural adsorbents, underscoring the significance of sustainable approaches in the treatment of wastewater. These findings contribute significantly to developing green solutions, showcasing the feasibility of utilizing bamboo and mango leaves in addressing diverse dye contaminants. Further optimization and mechanistic understanding are crucial for enhancing the efficiency of these eco-friendly adsorbents, paving the way for environmentally conscious water treatment practices.
