Interfacial mechanisms governing tetracycline adsorption on a valorized gasification slag–coal gangue composite

Key Points

• Tetracycline adsorption is significantly influenced by interfacial mechanisms, enhancing removal efficiency.
• The study shows a notable increase in adsorption capacity up to 45% in specific composite conditions.
• This analysis employs various characterization techniques to evaluate adsorption in gasification slag and coal gangue composites.
• Findings suggest the potential for these composites in wastewater treatment, although large-scale implementation still needs evaluation.
