“…Mordenite is the only phase that identified in calcined zeolite XRD data, so there is no change in mineral phase of zeolite, the structure remains intact after calcination. This data support the reports which state that calcination treatment above 500 °C could change zeolite into siliceous phase (quartz or cristobalite) or a compact aluminosilicate (labradorite) or amorphous solid, which means the lost porosity (Tišler et al, 2019;Trisunaryanti et al, 2018;Wahono et al, 2019).…”

“…7H2O. Mordenite is one of the most abundant zeolite minerals and commercially used for many purposes including adsorbents, catalyst, fertilizer, and gas separation (Klunk et al, 2020;Trisunaryanti et al, 2018;Wahono et al, 2019). Mordenite has shown better chemical resistance, a larger quantity of pore volume, good thermal stability, and high surface area (Narayanan et al, 2020).…”

Natural zeolites are available in Indonesia in very large quantities and are available in the market at very affordable prices. The use of zeolite has developed in various fields of industry, water treatment and wastewater treatment. The study on the ability of local natural zeolite to adsorb copper from acidic wastewater from a laboratory in Tangerang has been conducted. XRD data show that the local natural zeolite consists of mordenite as main mineral and quartz as an accessory mineral. Acid activation of zeolite with HCl 3 M could remove quartz impurities from natural zeolite based on XRD data. Mordenite is one of the most abundant zeolite minerals and commercially used for many purposes including adsorbents, catalyst, fertilizer, and gas separation. The crystallinity of mordenite decreases throughout the process of acid activation and calcination. The calcined zeolite has better copper adsorption ability compared to local natural zeolite without any treatment. The optimum copper adsorption percentage is 14.554% at solution pH of 0.3 by using 10 grams of calcined zeolite in 200 mL of wastewater solution.

“…In addition, to increase specific surface area, other changes in the material properties also occurred, as supported by a published study on dealumination and calcination treatment effect on natural zeolite. [ 44,45 ] The XRD, SEM, and XRF analyses are shown in Figures 1a, 1b, and 1d, respectively. The SEM images suggest greater porosity at the mesoscale after modification as well as a cleaner structure.…”

Solution‐based amine absorption technologies have been widely applied for CO2 capture, but they have several drawbacks. This paper reports on the synthesis of the first solid‐state amine adsorbent prepared through a simple plasma polymerization and deposition on physicochemically modified natural mordenite–clinoptilolite zeolite. The plasma deposition of amine polymer under certain conditions resulted in a significant increase in surface area‐weighted CO2 adsorption capacity as the natural zeolite. The strength of the interaction between CO2 and the adsorbent was weaker for the plasma polymer‐modified zeolite than without the plasma coating, which may facilitate regeneration. Both indications make the amine plasma polymer‐based zeolite adsorbent a good candidate for CO2 adsorption and separation.

“…Several Indonesian areas with a large number of zeolites are West Java (185.595.160 tons), South Sulawesi (169.880.000 tons), Lampung (43.800.000 tons), West Sulawesi (26.400.000 tons), West Sumatra (16.200.000 tons), and East Nusa Tenggara (6.115.000 tons) [1,2,3]. Generally, the types of natural zeolites in Indonesia are mordenite and clinoptilolite [4].…”

Effect of NaOH Concentration Toward the Characteristics of Activated Natural Zeolite from Blitar – East Java

2023

View full text Add to dashboard Cite

This study discusses the activation of natural zeolite from Blitar City – East Java using NaOH solution (0.5 M and 1.0 M). Characteristics of unactivated and activated zeolites were also investigated, as well as the effect of the activator (NaOH solution) on functional groups, element composition, pore size, specific surface area, and total pore volume. FTIR spectroscopy, XRF, and gas physisorption were conducted to support the study. Experimental data showed that: (1) the major functional groups were observed at 1250-780 cm-1 in the infrared spectra, in which the unactivated and the activated zeolite were not significantly different; (2) the elemental composition of zeolite (Si and Al) tended to decrease after the activation process; (3) the pore size of the activated zeolite increased while the surface area and total pore volume decreased. Based on this study, activated zeolite (AZB-1.0) showed the optimum result: the pore size increased by 4.12847 nm, and the total pore volume did not decrease significantly by 0.04987 cc/g.
