Enhanced adsorption of methyl orange using polyaniline-modified hydroxyapatite derived from natural Moroccan phosphate

Key Points

• Adsorption of methyl orange increased significantly, enhancing pollutant removal efficiency.
• The polyaniline modification improved hydroxyapatite's ability to capture the dye, achieving optimal results.
• Assessment using synthesized polyaniline-modified hydroxyapatite highlighted its potential for dye treatment applications.
• The findings support using natural phosphate-derived materials for environmental remediation efforts.
