The aim of present research is to evaluate the decontamination of nerve agent sarin simulant dimethyl methyl phosphonate (DMMP) in water media using the CuO/ZnFe۲O۴/NaA zeolite as a novel ternary nanocomposite adsorbent. In this regard, the CuO and ZnFe۲O۴ nanoparticles were successfully synthesized within the NaA zeolite applying the ultrasound-assisted hydrothermal route and characterized via XRD, FESEM, FTIR, EDAX, VSM and BET analyses. Then, the CuO/ZnFe۲O۴/NaA nanocomposite activity was investigated for the decontamination of DMMP molecule and monitored by a GC-FID and GC-MS analyses. Plus, the impacts of several parameters, including contact time, adsorbent dose and adsorbent type on the decontamination of DMMP were studied. The gained data from GC-FID analysis confirmed the maximum decontamination more than ۹۸.۴% for DMMP. The parameters including: adsorbent amount of ۵۰ mg and contact time of ۴۰ min were achieved as the optimized values for the decontamination reaction. In addition, the non-toxic methyl phosphoric acid (MPA) as the DMMP degradation product in the presence of CuO/ZnFe۲O۴/NaA adsorbent was characterized.
