What is it about?
This study explores the use of Haloxylon salicornicum (HS) as a natural, low-cost adsorbent to remove the toxic dye, crystal violet, from water. The adsorbent was characterized using FT-IR, XRD, SEM, and BET analyses, revealing its mesoporous structure. Adsorption efficiency was tested across various conditions, showing enhanced dye removal at higher dye concentrations, contact time, and pH. The kinetics followed a pseudo-second-order model. Additionally, theoretical methods, including DFT, MD simulations, and COSMO-RS, were employed to understand the interactions between the dye and the adsorbent, confirming strong binding interactions. The study highlights the synergy of experimental and modeling approaches.
