Abstract
At the present time, zeolitic imidazolate framework-8 is used in multiple areas from wastewater treatment, membranes, drug delivery and catalysis to photo electronics owing to their inherent exclusive pore structure and high specific surface area as well as their advanced thermal and chemical stability. The molecular differentiation qualities of the product that is ZIF-8 will affect by porosity and pore size distribution and this affects the membrane performance in terms of permeability. Systematic porous materials are broadly achieved by classical hard and soft templating techniques leading to diverse pore size distributions and morphologies. In recent years, ZIF-8 derived from Metal-organic frameworks (MOFs) which is a subclass of Metal-organic frameworks (MOFs) and these MOFs are growing as a novel category of nanoporous materials with large surface areas and small pore size distributions. In the present work, we have synthesized and characterized carbonized metal–organic framework, in the case of ZIF-8 for wastewater treatment processes. Nano ZIF-8 is prepared via a single step room temperature crystallizationwith 2-MIM and zinc nitrate hexahydrate as precursor materials. Prepared ZIF-8 materials were characterized by DLS, XRD, and SEM analysis for identifying morphological and compositional changes. Carbonized ZIF-8 (CZIF-8) is produced via the single-step carbonization technique by decomposing ZIF-8 in an inert atmosphere at 1000 °C. Parent material is compared with the carbonized material for morphological and elemental composition changes. ZIF-8 and CZIF-8 were utilized as an additive in the fabrication of a mixed matrix membrane to modified polysulfone membrane for wastewater treatment. As a result, compared with plain polysulfone membrane has a pure water flux of 50.5L/m2h and ZIF-8/PSF Mixed Matrix Membrane has a pure water flux is 456.09 L/m2h, but CZIF-8/PSF MMM is 521.12 L /m2 h, which is much greater than that of pure PSF and 4 wt% ZIF-8/PSF membranes. as shown in Fig 0.7.
