In this study, zeolite Y was synthesised using a novel method. The heat generated from the reaction of H2SO4 with metakaolin was used as a heat source instead of applying external heat for the dealuminated process. The synthesised zeolite Y produced was analysed by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier-infrared spectroscopy (FTIR), energy dispersive X-ray spectroscopy (EDS) and Brunauer–Emmett–Teller (BET). Zeolite Y synthesis was mesoporous because of its pore diameter (30.53 nm), as shown in the BET results. Surface area and pore size decrease after adsorption due to dye deposition on the adsorbent’s surface. FTIR has bonds like O–H, C–H, –CH3, and –COOH responsible for adsorption. The maximum adsorption capacity of eosin yellow (EY) and methyl orange (MO) on to zeolite Y by the Langmuir isotherm was 52.91 mg/g and 20.62 mg/g respectively, at pH 2.5 and 8 for EY and MO dye. The batch adsorption studies were conducted, and the influence of different parameters (i.e., adsorbent dose, adsorption time, initial dye concentration, pH and temperature) was investigated. Experimental data were analysed by two linear model equations (Langmuir and Freundlich isotherms), and it was found that the Langmuir isotherm model best describes the adsorption data for methyl orange and Freundlich isotherm for eosin yellow, respectively. Adsorption rate constants were determined using linear pseudo-first-order and pseudo-second-order. The results showed that MO and EY dye adsorption onto zeolite Y followed a pseudo-second-order kinetic model. Thermodynamic studies show that adsorption was an exothermic reaction (enthalpy < 0) and feasible ($$(Gibbs free energy)<0$$ ( G i b b s f r e e e n e r g y ) < 0 ) at various temperatures under investigation.

“…These absorption bands correspond to Si/Al-O asymmetry stretching vibrations (Deng et al, 2016;Safitri et al, 2020). Absorption bands that indicate the presence of zeolite appear in the 500-420 cm -1 region (Jumaeri et al, 2013).…”

Eutrophication is a phenomenon of decreasing air quality caused by the very high amount of phosphate ions in the aquatic system. Thus, an effective and efficient adsorbent is needed for phosphate absorption in aquatic systems. In this study, zeolit from fly ash waste was modified with zirconium (Zr) as an adsorbent for phosphate absorption in aquatic systems. Fly ash was pretreated with acid and then synthesised using the hydrothermal method. And then, the results of the fly ash zeolit synthesis were continued using zirconium. The adsorption capacity was tested through several parameters, including the adsorbent concentration test, variations in pH,and contact time. Zirconium-modified zeolite (ZrMZ) adsorbent was the most effective adsorbent for phosphate adsorption, with an adsorption capacity of 3.015 mg-P/g at a 3 g/L adsorbent dosage and pH 7. The adsorption kinetics for the ZrMZ adsorbent followed pseudo-second-order kinetics. The best result of ZrMZ adsorbent to absorb phosphate in lake water was an adsorption capacity value of 0.186 mg-P/g and an adsorption efficiency of 81.137%.

“…Figure 4 shows that acid-activated metakaolin has a different morphology than the parent kaolin [37]. Moreover, the micrograph of raw kaolin showed the structure consists of large size particles, the formation of agglomerates due to a stacked needle-like structure which causes poor dispersion of particles [38]. After acid activation, the morphological differences are apparent at high magnification.…”

High production of biodiesel results in a surplus of glycerol as a byproduct that leads to a drastic decline in the glycerol price as well as overall biodiesel production. Alternative methods must be introduced for the economical process for biodiesel production via utilization of crude glycerol into valuable chemicals or fuel additives. This study introduces an ecofriendly process of solketal synthesis from glycerol and acetone in the presence of a novel metakaolin clay catalyst, which is a useful additive in biodiesel or gasoline, in order to enhance the octane number and to control the emissions. Moreover, kaolin clay catalysts are low cost, abundantly available, eco-friendly and one of the more promising applications for solketal synthesis. In this study, raw kaolin clay was activated with an easy acid activation technique, modification in physicochemical and textural properties were determined by using X-ray diffraction (XRD), Fourier Transform Infra-Red (FTIR) spectroscopy, Brunauer–Emmett–Teller (BET) and Field Emission Scanning Electron Microscope. Among all acid-treated catalysts, metakaolin K3 have shown best catalytic properties, high surface area and pore size after acid activation with 3.0 mol/dm3 at 98 °C for 3 h. Acetalization of glycerol with acetone carried out in the presence of an environmentally friendly and inexpensive novel metakaolin K3 catalyst. The maximum yield of solketal obtained was 84% at a temperature of 50 °C, acetone/glycerol molar ratio 6/1 and for 90 min with novel metakaolin clay catalyst. Effect of various parameters (time, temperature, acetone/glycerol molar ratio, catalyst loading) on the solketal yield and glycerol conversion was discussed in detail. This approach offers an effective way to transform glycerol into solketal—a desirable green chemical with future industrial applications.
