Membrane technology is applied in several industries due to the advantages of being environmentally friendly and energy efficient. An in-depth examination on the impact of membrane Polyetheretherketone/Polyvinylalcohol (PEEK/PVA) composite modified with nanoparticle zinc oxide (ZnO) on particle size, mechanical, and morphological properties. Scanning electron microscopy (SEM) was applied for studying the dispersion of ZnO particles in PEEK/PVA composite. The characterization of the obtained hybrids was done using Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD) with an increase in the solubility of the gas molecules within the polymer matrix, an increase in the CO2 permeability is observed. The outcomes of the N2 permeability confirmed that the permeability of this agent undergo reduction with increasing pressure. Separation process at high pressures was proven since the selectivity of CO2/N2 boosted from 93.8 at 1 bar pressure to 43.6 at 8 bar pressure, with increasing feed pressure. The careful and detailed examination of the permeability and selectivity of CO2/N2 for membrane PEEK/PVA/ZnO nanoparticle modified with PEEK/PVA composite was performed. An increase in the CO2 permeability to the membrane PEEK/PVA from 19.6 to 87.7 upon modifying the surface area of the membrane PEEK/PVA/m-ZnO NPs (1.0 wt%, 2.0 wt% and 3.0 wt%), and increasing the percentage of this additive in the polymer matrix. Increase was due to the presence of cavities developed in the process of surface modification, and the increased of free volume and solubility of CO2/N2 inside the polymer membrane.

The applicability of Zeolitic Imidazolate-67 Modified by Fe3O4 Nanoparticles, was studied for eliminating butyl paraben dye from aqueous solutions. Identical techniques including BET, IR, XRD, and SEM have been utilized to characterize this novel material. The impacts of variables including initial butyl paraben concentration (X1), pH (X2), adsorbent dosage (X3), and sonication time (X4) came under scrutiny using central composite design (CCD) under response surface methodology (RSM). Additionally, the impacts of the pH of the solution, the amount of nanoparticles, concentration of butyl paraben dye, and contact time were investigated. The experiments have been designed utilizing response surface methodology. In this current article the values of 10 mgL-1 , 0.03 g, 7.0, 4.0 min were considered as the ideal values for butyl paraben concentration, adsorbent mass, pH value and contact time respectively. The kinetics and isotherm studies proved the appropriateness of the second-order and Langmuir models for the kinetics and isotherm of the adsorption of butyl paraben on the adsorbent. The adsorbent was proved to be recyclable for more than once. Since almost 99.5% of butyl paraben was deleted with ideal adsorption capacities of 110 mgg−1 for butyl paraben in no time, therefore not only the short-time adsorption process was considered an advantage but also vantages in using Zeolitic Imidazolate-67 Modified by Fe3O4 Nanoparticles like being recyclable, safe, and cost-efficient made it a promising and powerful material for the aqueous solutions.
