Cetyltrimethylammonium Bromide-Modified Laponite@Diatomite Composites for Enhanced Adsorption Performance of Organic Pollutants

Langmuir, Journal Year: 2024, Volume and Issue: 40(16), P. 8427 - 8439

Published: April 12, 2024

This work aims to enhance the adsorption performance of Laponite @diatomite for organic pollutants by modifying it with cetyltrimethylammonium bromide (CTAB). The microstructure and morphology CTAB-modified material were characterized using SEM, XRD, FTIR, BET, TG. Furthermore, influences key parameters, containing pH, adsorbent dosage, reaction time, temperature, on process investigated. kinetics, thermodynamics, isotherm models analyzed. Finally, potential mechanisms given based characterization. research findings indicate that CTAB-La@D exhibits good toward Congo red (CR) over a broad pH range. maximum capacity CR was 451.1 mg/g under optimum conditions (dosage = 10 mg, contact time 240 min, initial concentration 100 mg/L, temperature 25 °C, 7). conformed pseudo-second-order kinetic model, isotherms indicated more in line Langmuir physical adsorption. Thermodynamic analysis illustrates is exothermic spontaneous. Additionally, electrostatic hydrophobic effect investigated through XPS FTIR analysis. provides an effective pathway designing high-performance adsorbents removal dye, synthesized materials hold great capability practical utilization treatment wastewater.
