Removal of Hexamethyldisiloxane by NaOH–Activated Porous Carbons Produced from Coconut Shells

The utilisation of activated porous carbon (APC) for the removal volatile methyl siloxane (VMS) has attracted significant research attention. However, development materials with high adsorption capacity remains a challenge. In this study, we successfully developed high-specific-surface-area (2551 m2 g−1) APC material large texture (1.30 cm3 using coconut shell waste and NaOH as activating agent. performance in hexamethyldisiloxane (L2) was evaluated fixed-bed dynamic setup. Notably, at 0 °C, demonstrated remarkable L2 ability, achieving breakthrough 898.6 mg g−1. By increasing inlet concentration decreasing temperature appropriately, could be further improved. One advantage APCs is their simple recycling process, which allows sustained even after five consecutive cycles desorption. Therefore, prepared holds great promise an efficient adsorbent VMS.
