“…Besides, geopolymer membrane could be prepared through simple way by hydrogen peroxide and albumen (surfactant), which obtained the total porosity of 74.29% . Duan et al used fly ash as raw materials for fabrication of geopolymer with the improved adsorption of Cu 2+ (maximum capacity: ~113 mg/g).…”

A novel porous coal gangue microsphere/geopolymer (CG/KGP) composite was firstly synthesized by adding gangue microspheres into geopolymer matrix. Effects of precalcined temperature of CG microspheres on the microstructure and specific surface area of the porous CG/KGP particles were systematically investigated. Adsorption properties of the CG/KGP composites were also reported. Results showed that the CG/KGP composites contained mainly amorphous phase and many functional groups were on the particle surface. The precalcined CG microspheres were dispersed homogenously and bonded well with the KGP matrix. The CG900/KGP samples showed better adsorption properties than the pure KGP. As for the dosage of 4 g/L (starting concentration, 100 mg/L), adsorption capacity achieved the highest value of 24.6 mg/g and the removal efficiency reached 98%. Adsorption of MB onto CG900/KGP particles followed the pseudo‐second‐order kinetic model. The novel porous CG/KGP composite has potential application in wastewater filtration and adsorption treatment.

As the environment deteriorates, recycling of solid waste has become increasingly important. This study aimed to optimize the use of the Fe2O3, SiO2, and CaO components in coal fly ash and to convert coal fly ash into stable porous Al2TiO5‐mullite (AT–M) composite ceramic by sintering with AlOOH and TiO2 additives at high temperatures. The phase composition, microstructure, apparent porosity, corrosion resistance, and mechanical properties of porous AT–M composite ceramics were systematically investigated. Results indicated that the sintered samples exhibited pore size distributions within the 0.16‐2.9 μm, apparent porosities of approximately 52.8%, and flexural strength of 29.6 MPa. Corrosion resistance data revealed quality losses in the aqueous NaOH and H2SO4 solutions for 10 hours at 0.42% and 2.19%, respectively. After corrosion for 8 hours, the average flexural strength of the samples remained at 21.6 ± 0.53 and 20.84 ± 0.6 MPa, respectively. These findings show that these porous AT–M ceramics may provide enhanced corrosion resistance under alkaline conditions. The porous AT–M composite ceramics may fabricate high‐performance composite membrane supports for the high temperature flue gas filtration.

“…Removal by adsorption process is our major focus because the process was simple and effective [5]. Absorbents used in previous studies for heavy metal removal by adsorption process were activated carbon [4] and Zeolite [7]- [9]. A new type of absorbent material that has potential to be used for heavy metals adsorption is metal-organic frameworks.…”
