Acid recovery from acidic waste is a critical issue to be focused on nowadays. Chem. approaches for recovery are not com. viable and energy intensive to save the environment. Here, we report internally crosslinked poly (2,6-dimethyl-1,4-phenylene ether) (PPE) based anion exchange membranes (AEMs) for acid recovery by diffusion dialysis, prepared via quick grafting of N-methyl-4-piperidone using ultrasonication. The prepared AEMs are assessed for their physicochem. parameters and depicted water uptake (WU) and ion-exchange capacity (IEC) in the range 22.00%-31.00% and 0.64 meq/g-2.18 meq/g resp. for Cl-1, NO-3 and SO2-4 ions. AEMs were investigated for recovery of hydrochloric acid (HCl), nitric acid (HNO3) and sulfuric acid (H2SO4) from simulated effluent based on their proton diffusion coefficient (U+H), separation factor (S) and recovery efficiency. These membranes illustrated the proton diffusion coefficient as high as 0.065 m h-1 and enhanced separation factor values up to 132 at 27°C. Recovery performance for different acids is corroborated based on unique self-organized membrane structure, studied using AFM phase imaging and cumulative influence of bulk diffusion coefficient, ion-exchange capacity, and hydration radii of Cl-1, NO-3 and SO2-4 ions. The acid recovery efficiency illustrated the trend HCl > HNO3 > H2SO4. The hydrate (-OH) functionality with a non-overlapping set of lone pairs on oxygen enhances the proton mobility via Grotthuss mechanism inside the membrane matrix and provides a cradle-like pathway for high proton mobility. The results are pronounced for fabricated membranes compared to com. available standards for acid recovery via diffusion dialysis. In addition to this study using 1-Methyl-4-piperidone, there are many other studies that have used 1-Methyl-4-piperidone(cas: 1445-73-4Safety of 1-Methyl-4-piperidone) was used in this study.
1-Methyl-4-piperidone(cas: 1445-73-4) is a member of piperidine. Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Hence, continuous efforts have been made to develop convenient methods to prepare piperidine derivatives.Safety of 1-Methyl-4-piperidone
