“…As seen, VAS was clearly dominated by amorphous quartz as the major phase that appeared on the sample. The VAS pattern was similar characteristics to the Bali pumice sample in our previous study [22]. When VAS was treated under the alkaline condition and followed by the hydrothermal process, the amorphous content decreased.…”

This study demonstrates the potential use of volcanic ash soil (VAS) as raw materials for preparing zeolite without adding any templates or seeds. Here we investigated the effect of alkaline concentrations on the synthesis of VAS-based zeolite and enhanced its ability for methylene blue (MB) removal by Fenton-like process. Zeolite materials were directly synthesized by mixing the amount of VAS within alkaline concentrations of 0.5 (P1), 1.5 (P2), and 3.0 mol/L (P3), respectively, followed by a simple hydrothermal procedure at 100 oC for 24 h. The prepared sample characteristics were obtained from the Fourier transform infrared (FTIR) and X-ray diffraction (XRD) analysis, which confirmed the formation of zeolite A and some mineral phases in P2 and P3 samples. The mentioned samples reached equilibrium state at MB concentration of 200 mg/L with high adsorption capacity values compared to VAS. The adsorption showed a better fit to the Langmuir isotherm model (R2]0.99), in which the maximum uptake capacities were found to be 24.03 mg/g for P2 and 14.30 mg/g for P3. Interestingly, the percentage of MB removal using P2 and P3 increased greatly from 52.81% and 32.26% to 98.92% and 98.85% by Fenton-like process, respectively.

“…In the literature, according to Ersoy et al [22], the peaks at 400 cm −1 and 800 cm −1 of the pumice samples might have been associated with the Si-O, while the strong peak at around 1,100 cm −1 was related to Si-O stretching vibrations. Also, as stated by Prajaputra et al [23], the peaks at ~720, 1,000, 1,650, and 3,475 can be described as the bending vibration of the Si-O-Si bond. Similar peaks [(SiO 4 ) −2 group: Si-O-Si, H-O, H-O-H, etc.)…”

The scope of the study involves identifying the optimal means to effectively use the electrospinning technique to obtain pumice-containing nanofibers. Nanofiber containing pumice in a solution was electrospun to obtain smooth, cylindrical, bead-free, and ultrafine nanomaterials. The study also analyzed the molecular [Fourier transform infrared spectroscopy (FTIR)], thermal [differential scanning calorimetry (DSC)], zeta potential, size, polydispersity index [dynamic light scattering (DLS)], and surface [scanning electron microscope (SEM)] parameters of the pumice-containing nanofibers having JP6 (applied voltage: 6 kV) and JP12 (12 kV) properties. While the distance (10 cm), flow rate (0.8 mL/h), and other parameters of the electrospinning process were fixed, two different voltages were applied to obtain the pumice-containing nanofiber. The average diameter of the nanoencapsulated pumice produced at 6 kV was defined as 98.6 nm in gelatin nanomats with 31.8 nm. The average diameter of the nanocapsule pumice produced under a 12 kV voltage was found to be 85.8 nm, and the average diameter of the nanomats (non–nanoencapsulated) was 35.2 nm. The average zeta potential values of the pumice-containing nanofiber were also determined in the nanosize range. The JP6 and JP12 PDI values were determined as 0.165 and 0.566, respectively. Peaks characteristic of pumices as defined in the literature were observed in the FTIR results, while DSC analysis results revealed strong endo- and exothermic peaks. As a result of this study, it has been proved that pumice can be reduced to nanosize with the electrospinning technique and it is nanoencapsulated in nanofiber. When the obtained pumice-containing nanofiber was examined, it was determined that the surface area of the nanofiber was large and resistant to thermal heat.

“…Furthermore, the alkaline activation process created additional pores due to reduction and oxidation reactions causing a decrease in pores from 19.84 to 3.865 nm [56]. The improvement in material pore volume is attributed to the rearrangement of the composite structure due to the increasing number of pores [57]…”

The recycling of waste materials in wastewater decontamination has been an attractive discipline in zero discharge and energy recovery. Biochar/zeolite nanocomposite has been successfully synthesized as a cheap and eco-friendly material from a solid fraction obtained from the thermos-catalytic conversion of green pea agriculture waste (Pisum sativum). A dark-whitish solid was obtained from thermal pyrolysis at 450 °C with a heating rate of 27 °C/min for 15 min that was further subjected to alkaline chemical activation. The synthesized composites have been examined using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD), transmission emission microscopy (TEM), and Brunauer-Emmet-Teller (BET) analyses. The successful preparation of biochar/zeolite nanocomposite was evident from characterization results with an average particle size of 30–40 nm with a high surface area of 15.3 m2/g. The material was evaluated as an eco-friendly adsorbent for decolorization of both cationic methylene blue dye (MB) and Congo red anionic dye (CR) using the batch technique. The influence of dosage, pH, temperature, initial dye concentration, and contact time were studied against the dye adsorption process. It was indicated that the material recorded maximum dye decolorization efficiencies of 87.5% at pH of 12 and 84.1% at pH of 2 for MB and CR, respectively. The optimum material dosage and contact time for dye decolorization were 5 g/l and 60 min, respectively. Thermodynamic parameters were calculated from the sorption process and revealed a negative charge of Gibbs free energy ($${\Delta G}^{o}$$ Δ G o ) an indication of spontaneity and thermodynamic favorability. Positive enthalpy and entropy demonstrated the endothermic behavior and the disorderliness. Equilibrium adsorption results best fitted to the Langmuir isotherm model, while MB and CR adsorption kinetics were pseudo-second-order reactions.
