“…Recent studies have indicated that soda-lime-silica container glass is a potentially useful feedstock for the facile one-step hydrothermal synthesis of various impure zeolites [6][7][8][9]14,[21][22][23][24][25]. In the absence of pre-conditioning, the presence of 6-12 wt% CaO in container glass restricts the hydrothermal products to small-pore low-silica zeolites that tolerate in situ Ca 2+ incorporation during crystallisation and also gives rise to other, more dense, calcium aluminosilicate phases such as tobermorite and katoite [9,14].…”

“…Hence, in comparison with other silicate wastes, such as slags and fly ashes, container glass of any origin provides a relatively predictable source of silica with negligible concentrations of toxic components [7][8][9]. The reactivity of the amorphous silica species in container glass under mild hydrothermal conditions has been exploited in several studies to produce a range of technologically relevant mineral phases including tobermorite (Ca 5 Si 6 O 16 (OH) 2 •4H 2 O) [3,[17][18][19], lithium metasilicate (Li 2 SiO 3 ) [9,15,20] and various zeolites [6][7][8][9]14,[21][22][23][24].…”

“…To date, impure low-silica zeolites (i.e., Si/Al molar ratio <2), such as A, F, P, X, sodalite, cancrinite and analcite, have been prepared from stoichiometrically adjusted mixtures of container glass and aluminium-bearing reagents in aqueous alkaline media under convection and microwave heating [6][7][8][9]14,[21][22][23]. Typical one-step hydrothermal syntheses involve autoclaving ground glass (<2 mm) with an aluminium reagent (Si/Al molar ratio 1-10) in alkali metal hydroxide solution (0.5-8 M) between 60 and 200 • C for up to 14 days [6][7][8][9]14,[21][22][23][24].…”

This study investigated the one-pot hydrothermal synthesis of mixed-phase ion-exchangers from waste amber container glass and three different aluminium sources (Si/Al = 2) in 4.5 M NaOH(aq) at 100 °C. Reaction products were characterised by X-ray diffraction analysis, Fourier transform infrared spectroscopy, 27Al and 29Si magic angle spinning nuclear magnetic resonance spectroscopy and scanning electron microscopy at 24, 48 and 150 h. Nitrated forms of cancrinite and sodalite were the predominant products obtained with reagent grade aluminium nitrate (Al(NO3)3∙9H2O). Waste aluminium foil gave rise to sodalite, tobermorite and zeolite Na-P1 as major phases; and the principal products arising from amorphous aluminium hydroxide waste were sodalite, tobermorite and zeolite A. Minor proportions of the hydrogarnet, katoite, and calcite were also present in each sample. In each case, crystallisation was incomplete and products of 52, 65 and 49% crystallinity were obtained at 150 h for the samples prepared with aluminium nitrate (AN-150), aluminium foil (AF-150) and amorphous aluminium hydroxide waste (AH-150), respectively. Batch Pb2+-uptake (~100 mg g−1) was similar for all 150-h samples irrespective of the nature of the aluminium reagent and composition of the product. Batch Cd2+-uptakes of AF-150 (54 mg g−1) and AH-150 (48 mg g−1) were greater than that of AN-150 (36 mg g−1) indicating that the sodalite- and tobermorite-rich products exhibited a superior affinity for Cd2+ ions. The observed Pb2+- and Cd2+-uptake capacities of the mixed-product ion-exchangers compared favourably with those of other inorganic waste-derived sorbents reported in the literature.

“…These low carbon dioxide emissions can be predicted by geochemical modeling [54][55][56][57]. One of the existing technologies involves CO 2 capture post-combustion, using adsorption as a selective process where the constituent molecules in a mixture of gases adhere on the solid surface (zeolites) [26,[58][59][60][61][62]. The primary variables to be considered for adsorption are temperature, pressure and pore size [63].…”

Rice husk is considered as a waste in the rice industry but is proficient in manufacturing different materials, such as zeolites, which is produced in large quantities all over the world, for example in Brazil. Zeolite is an adsorbent support material, which can be synthesized from rice husk ash (RHA) with external sources of aluminium (ESA). The scientific community has been conducting several measures to minimize the environmental impacts caused by greenhouse gases. Several mitigation processes are presently investigated, which includes carbon dioxide injections into adsorbent materials (e.g. zeolites). The efficiency of this technology involves a zeolitic material with high crystallinity and high concentrations of SiO 2 and Al 2 O 3 (aluminosilicates). In the present work, zeolites have been synthesized from rice husk ash (SiO 2 source) and external aluminium sources (Al 2 O 3 -alumina, gibbsite and metakaolin) to fulfill that purpose. With the aid of XRF, XRD, SEM/ EDS and FTIR techniques, the zeolitic material was characterized in two distinct crystalline phases: Mordenite and ZSM-5. The synthesis was carried out by the ideal addition of ESA (2.5 g) to RHA. According to the literature, the zeolitic materials formed by the mixture of Mordenite and ZSM-5 can be availed for gas separation and greenhouse gas storage.

“…The acid mud can be neutralized using calcium oxide, however, larger volumes of solid waste are generated with the subsequent environmental problems associated. One strategy to mitigate this situation is the use of acid mud in construction applications or preparation of several types of materials, such as zeolites . Zeolites are microporous aluminosilicate materials with more than 200 of synthetic zeo‐types.…”

The use of acid mud produced during the aluminum extraction of kaolinite to synthesize mobil composition of matter no. 41 (MCM‐41) type material is proposed in this work. The acid mud was placed in contact with NaOH at 550°C to release the silicon and aluminum, then the fused material obtained was mixed with cetyltrimethylammonium bromide (CTAB) followed by a hydrothermal treatment considering a factorial design 2k with four experimental factors (CTAB dose, synthesis time, temperature, and solid/liquid ratio). The formation of MCM‐41 was evaluated via X‐ray diffraction (XRD) and scanning electron microscopy coupled with electrons dispersive spectroscopy (SEM‐EDS) analysis complemented with surface area analysis from which a maximum value of 550 m2/g was obtained for the best material. XRD results showed the typical pattern of MCM‐41 measured at low angle, furthermore, the characteristic type IV isotherm of adsorption–desorption was observed in certain materials. The elemental analysis showed the presence of iron and titanium oxide, which could be of great interest for the use of the material as a photocatalyst. Preliminary tests, using the MCM‐41 samples synthesized and methyl orange revealed a moderate photocatalytic activity of the material as compared to a commercial product (P25); opening up opportunities for the further development of such materials as potential and cost‐effective photocatalysts for pollutants degradation in wastewater. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13069, 2019
