摘要

In the current global scenario, the potential use of toxic industrial gases (TICs), chemical warfare agents (CWAs), and their combination poses a significant threat, particularly by the state actors, raising serious concerns for the global community. This study focuses on the design, material composition, and performance evaluation of adsorbent materials capable of providing simultaneous protection against both CWAs and TICs. Herein, materials were developed by incorporating various surface functionalities along with introduction of catalytic centers in the carbon matrix. To address the vast spectra of CWA and TICs, three distinct adsorbent materials were prepared; the first comprising of catalytic centers of Cu, Ag, Zn, Mo and the organic amine TEDA (triethylenediamine) to facilitate chemisorption and neutralization; the second was acid treated carbon to enrich the surface functionalities along with CuCl2 and KI, and the third comprised of CuCl2, NaOH and KI. To confirm the modification, adsorbent materials were characterized utilizing SEM, EDS, elemental mapping, FT-IR, TGA, PXRD, BET analysis and pore size distribution analysis. A final composite formulation, optimized by mixing the adsorbents in appropriate ratios was evaluated against CWAs simulant CCl4, and TICs (NH3, SO2, Cl2, H2S) and blood agents HCN and found to be effective against broad-spectrum efficacy as per EN 14387 standard. This study will pave the way for the development of next-generation adsorbent materials that provide a unified and practical solution for respiratory protection against a wide spectrum of toxicants, specifically designed for first responders during chemical emergencies.
