Ultra-selective and highly efficient adsorption of anionic/cationic dye by AgBiS2 and mechanistic analysis

Key Points

• Adsorption efficiency increases significantly for both anionic and cationic dyes with AgBiS2, demonstrating its broad applicability.
• Key results showed over 90% dye removal within 30 minutes for anionic and cationic dyes, underscoring its rapid functionality.
• Mechanistic analysis indicates strong interactions between the dye molecules and AgBiS2's surface, enhancing the adsorption process.
• These findings support the potential of AgBiS2 in wastewater treatment applications, requiring further large-scale studies.
