Adsorption of sodium lauryl sulfate onto calcium-phosphate hydroxyl@clay hybrid adsorbents.

ABSTRACT: This work investigated the use of clay (C), calcium phosphate hydroxyl (CPH), and a nanocomposite of calcium phosphate hydroxyl@clay (CPH@C) for the removal of sodium lauryl sulfate surfactant from aqueous solutions. Sorption efficiency was assessed based on parameters like adsorbent dosage, contact time, surfactant concentration, temperature, and pH. Structural elucidation of the adsorbents was performed out using FT-IR spectroscopy, SEM, and XRD. Optimal sodium lauryl sulfate surfactant uptake was achieved under the following conditions: temperature of 55 °C; shaking time of 60 min for clay and CPH, and 80 min for CPH@C; surfactant concentration of 150 mg/L; pH values of 4.0 for clay, 6.0 for CPH, and 5.0 for CPH@C; and adsorbent dosage of 0.7 g for clay and CPH, and 0.5 g for CPH@C.
