The infrared spectra of the five BBG samples were recorded with a Fourier transform infrared spectrometer (FT-IR, Nicolet 670, Thermo Scientific, Waltham, MA, USA) in the range 4000–400/cm using the KBr-disk method [29 (link)]. One-dimensional proton NMR measurements of the samples were analyzed on a 700 MHz NMR spectrometer (Bruker Advanced III HD, Bruker, Billerica, MA, USA) at 60 °C using DMSO-d6 as the solvent [30 (link)].
Nicolet 670
Manufactured by Thermo Fisher Scientific
Sourced in United States
The Nicolet 670 is a Fourier Transform Infrared (FTIR) spectrometer designed for laboratory use. It is capable of analyzing the infrared absorption and transmission properties of a wide range of samples, including solids, liquids, and gases. The instrument uses an interferometer to generate and detect infrared radiation, allowing for rapid and accurate spectral measurements.

The microstructures of the hybrid structures based on graphene sheets are characterized by scanning electron microscope (SEM) images and EDS spectra, taken with a Carl Zeiss SUPRA 55VP FE-SEM. For revealing the compositions of the hybrid structures, X-ray diffraction(XRD) analysis was performed on a Bruker New D8-advance X-ray diffractometer equipped with Ge-monochromatized Cu Kα radiation (λ = 1.5418 Å). For Fourier transform infrared spectrometry (Thermo Scientific Nicolet 670), GO, EDTA-GO and EDTA-rGO were scanned from 500 to 4000 cm−1 in forms of buckypaper. Contact angle of GO, rGO, EDTA-GO and EDTA-rGO layer on PTFE filter was measured with KRÜSS DSA 100 instrument. Conductivity of ion solutions (MgCl2, NaCl and KCl solutions) before and after filtration for permeation rate was measured with Mettler Toledo SevenCompactTM conductivity meter. The concentration of positive and negative ions into the solution was measured with Shimdzu JP/ICPS-750 (inductively coupled plasma, ICP) and Dionex ICS-3000(Ion chromatograph, IC), respectively.

Comprehensive Characterization of E-TBBPA-MINs

Morphologies and/or elemental compositions of E-TBBPA-MINs and E-TBBPA-MIM were determined by scanning electron microscopy equipped with an energy-dispersive spectrometer (SEM-EDS, Tescan Mira4, Brno, Czech Republic), transmission electron microscopy (TEM, JEOL F200, Tokyo, Japan), and atomic force microscopy (AFM, Bruker Dimension Icon, Bremen, Germany). The surface functional groups and chemical states of key elements of SiO2 NPs, E-TBBPA-MINs, and NINs were measured with a Fourier transform infrared spectrometer (FTIR, Thermo Scientific Nicolet 670, Waltham, MA, USA) and X-ray photoelectron spectroscopy (XPS, Thermo Scientific Nexsa, Waltham, MA, USA). The PerkinElmer system was utilized to perform thermo-gravimetric analysis (TGA) of SiO2 NPs and E-TBBPA-MINs. A Brunauer–Emmett–Teller (BET, Micromeritics ASAP 2460, Norcross, GA, USA) analysis was conducted to compare the characteristics of N2 adsorption/desorption isotherm, specific surface area, average pore diameter, and pore volume of E-TBBPA-MINs, and NINs. Membrane-wetting behaviors of E-TBBPA-MIM and pristine PVDF membrane were evaluated using a contact angle meter (SDC 100S, Beijing, China). Measurements of the porosity and water permeability of these two membranes were conducted according to the procedures described previously [27 (link),28 (link)].
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
