“…Linearity of curves shows the kinetics of degradation of CWAs sarin and soman on Zr(OH) 4 @W-ACF (see Fig. 8 A and B ) follow the first order kinetics 85 , 87 . The regression coefficient (R 2 ) values for the first order kinetic model with CWAs sarin and soman was 0.973 and 0.981, respectively which indicates the applicability of the first order nature of degradation process on Zr(OH) 4 @W-ACF.…”

Chemical warfare agents (CWAs) have become a pivotal concern for the global community and spurred a wide spectrum of research for the development of new generation protective materials. Herein, a highly effective self-detoxifying filter consisting of in-situ immobilized Zirconium hydroxide [Zr(OH)4] over woven activated carbon fabric [Zr(OH)4@W-ACF] is presented for the removal of CWAs. It was prepared to harness the synergistic effect of high surface area of W-ACF, leads to high dispersion of CWAs and high phosphilicity and reactivity of [Zr(OH)4]. The synthesized materials were characterized by ATR-FTIR, EDX, SEM, TEM, XPS, TGA, and BET surface area analyzer. The kinetics of in-situ degradation of CWAs over Zr(OH)4@W-ACF were studied and found to be following the first-order reaction kinetics. The rate constant was found to be 0.244 min−1 and 2.31 × 10−2 min−1 for sarin and soman, respectively over Zr(OH)4@W-ACF. The potential practical applicability of this work was established by fabricating Zr(OH)4@W-ACF as reactive adsorbent layer for protective suit, and found to be meeting the specified criteria in terms of air permeability, tearing strength and nerve agent permeation as per TOP-08-2-501A:2013 and IS-17380:2020. The degradation products of CWAs were analyzed with NMR and GC–MS. The combined properties of dual functional textile with reactive material are expected to open up new exciting avenues in the field of CWAs protective clothing and thus find diverse application in defence and environmental sector.

“…To this suspension, a hot solution (70 °C) containing 21.28 g of magnesium acetate in 50 mL of isopropanol was added in drop wise manner. After complete addition and stirring for 1 h at 80 °C, suspension was filtered and dried at 100°C for 4 h. Obtained solid was calcined at 500 °C for 2 h to obtain MgO nanoparticles 17 .…”

Present paper relates to nanomaterials based decontamination formulation made up of TiO 2 , MgO, and ZnO nanoparticles for the use against chemical warfare agents. This decontamination formulation was prepared by mixing 90 per cent of TiO 2 nanoparticles of 5-15 nm size range, 8 per cent of MgO nanoparticles of 5-15 nm size range, and 2 per cent of ZnO nanoparticles of 20-30 nm size range. Prepared formulation exhibited 98-99 per cent of physical removal efficiency against contaminated glass, rubber, painted metal, metal surfaces. It efficiently removed chemical warfare agents from contaminated skin thus ameliorating chances of fatality which is expected due to skin penetrated chemical warfare agents. It also chemically degraded 97 per cent of sulphur mustard in 24 h, 99.9 per cent of sarin in 2 h, respectively unlike Fuller's earth which chemically degraded only 63 per cent of sulphur mustard and 59 per cent of sarin in 24 h .
