Abstract In this study, we have evaluated the performance of novel adsorbent zeolite Linde Type W and modified LTW with AgO metal oxide composite for the decontamination of chemical warfare agent simulant 2-chloroethylphenylsulphide (CEPS). Zeolites are nanoporous aluminosilicate minerals composed of silicon, aluminum and oxygen framework with cations and water molecules within the pores. The synthesized zeolite LTW and its composites Ag-O-LTW was characterized by XRD, FTIR, SEM-EDS and BET analytical techniques. The decontamination study of CWA simulant, CEPS was monitored by using GC-FID technique. The nanocrystalline zeolite LTW and Ag-O-LTW composites were found powerful adsorbents and showed great decontamination potential toward CWA simulant CEPS. The Ag-O-LTW showed better results (∼98 % decontamination in 7 hours) than LTW zeolite. Graphical Abtract

用于化学战剂模拟物去污的Linde W型沸石及其金属氧化物复合物Ag-O-LTW的合成与表征

摘要 在本研究中，我们评估了新型吸附沸石 Linde W 型和含有 AgO 金属氧化物复合物的改性 LTW 对化学战剂模拟物 2-氯乙基苯硫醚 (CEPS) 净化的性能。沸石是由硅、铝和氧骨架组成的纳米多孔铝硅酸盐矿物，孔内有阳离子和水分子。通过XRD、FTIR、SEM-EDS和BET分析技术对合成的LTW沸石及其复合材料Ag-O-LTW进行了表征。使用GC-FID技术监测CWA模拟物CEPS的去污研究。纳米晶沸石 LTW 和 Ag-O-LTW 复合材料被发现是强大的吸附剂，并显示出对 CWA 模拟 CEPS 的巨大净化潜力。Ag-O-LTW 显示出比 LTW 沸石更好的结果（7 小时内约 98% 的净化）。
