“…5A, in which, different characteristic adsorption bands were observed, such as: 3440 and 3200 cm −1 (N-H stretching), 2923, 2850, and 2765 cm −1 (C-H stretching), 1659 cm −1 (C=O stretching), 1446 cm −1 (C-H bending), and 1120 cm −1 (N-H stretching). These signals were similar to those reported by Dweik et al, (2008) and Nascimento et al, (2019).…”

“…Adsorption by ion exchange is a viable option, because of its high efficiency and simplicity. It is a process in which ions in aqueous solution are transferred (since they are attracted by electrostatic charges) to a solid matrix, which releases a different kind of ions with equal charge [20][21][22][23]. Zeolites and activated carbons are some of materials used for metal removal by adsorption due to their high surface area and porosity; however, these materials are quite expensive due to the depletion of raw material sources and the high energetic requirements of the synthesis process.…”

Microstructure and Pb2+ Adsorption Properties of Blast Furnace Slag and Fly Ash based Geopolymers

et al. 2020

In this study, a blast furnace slag (BFS) and fly ash (FA) based adsorbent geopolymer to be used for removing Pb2+ from aqueous solutions were synthesized using the hydrothermal method at 60 °C for 24 h, and then cured at 25 °C for another six days. The alkali activator applied in this work was a combination of sodium hydroxide and sodium silicate solutions at a mass ratio of 2. The geopolymer slurry was adjusted to a Si/Al molar ratio of 3. A BFS-based geopolymer (GS) having a specific area of 23.56 m2/g and pore size and volume of 7.8 nm and 73 cm3/kg, respectively, surpassed the raw material surface by approximately 13-fold. An FA-based geopolymer (GA) having a specific area of 35.97 m2/g and a size and porous volume of 9 nm and 124 nm, respectively, surpassed the raw material surface by approximately 23-fold. In addition, GS and GA showed a cation exchange capacity (CEC) of 241.30 and 286.96 Meq/100 g, respectively. X-ray diffraction (XRD) determined sample crystallinity and it was proven by scanning electron microscopy (SEM), showing that both geopolymers were constituted of unreacted particles surrounded by amorphous and semi-amorphous products. Through Fourier transform infrared spectroscopy (FTIR), a band that was assigned to the asymmetric stretching vibration of Si-O-M (M = Na+ and/or Ca2+) non-bridging oxygen type was observed, which suggested that Na and Ca could serve as exchangeable ions in the ionic exchange process. Adsorption test data indicated that good adsorption was obtained when a neutral pH was used at room temperature, and the adsorption isotherm showed that GA had more adsorption sites than GS, which meant greater maximum adsorption capacity.

“…A cromatografia de troca iônica (CTI) envolve um fenômeno físico-químico em que uma solução troca íons com a superfície de um sólido poroso (Guiochon, 2002). A vantagem do uso da CTI para proteínas é que a adsorção pode ser facilmente reversível com a mudança das condições do processo (Fidelis, 2011;Nascimento et al 2019).…”
