Recent progress in the preparation, characterization, and applications of modified halloysite nanotubes as adsorbents for wastewater treatment

An integrated experimental and theoretical approach to probe Cr(vi) uptake using decorated halloysite nanotubes for efficient water treatment

“…Various f-HNTs have shown promise as nano-sorbents due to the presence of oxygen and nitrogen-containing functional groups on their surface. 82,83 The adsorption efficiency of Cr( vi ) ions on f-HNTs was evaluated at optimized conditions including a pH of 3, a contact duration of 30 minutes, an adsorbate concentration of 10 ppm using 10 mg of the adsorbent. The optimal adsorption rates of Cr( vi ) ions on various f-HNTs ranged between 58% to 94% as depicted in Fig.…”
