“…They are used as a catalyst, adsorbents for wastewater treatment, removal of pollutants, etc. Currently, around 150 different synthetic zeolites are synthesized throughout the globe, which in total accounts for around 3 million tons of zeolites produced annually [50]. These have been synthesized and designed according to their needs for specific purposes.…”

The traditional hydrothermal synthesis methods are mainly performed under batch operation, which generally takes few days to weeks to yield a zeolite with the desired properties and structure. The zeolites are the backbone of the petrochemical and wastewater industries due to their importance. The commercial methods for zeolite synthesis are expensive, laborious and energy intensive. Among waste products, incense sticks ash is a compound of aluminosilicates and could act as a potential candidate for the synthesis of zeolites for daily needs in these industries. Incense sticks ash is the byproduct of religious places and houses and is rich in Ca, Mg, Al and Si. As a result, incense sticks ash can be proven to be a potential candidate for the formation of calcium-rich zeolites. The formation of zeolites from incense sticks ash is an economical, reliable and eco-friendly method. The application of incense sticks ash for zeolite synthesis can also minimize the problem related to its disposal in the water bodies, which will also minimize the solid waste in countries where it is considered sacred and generated in tons every day.

“…The market unit price of natural zeolite, vermiculite and biochar were $50-300 (Szerement et al 2021), $850 (Brião et al 2021) and $2062-2512(Campbell et al 2018 respectively. The corresponding cost for removing 1,000 g ammonia nitrogen was investigated and the smallest cost was $13 for zeolite (Table 3).…”

Combined treatments were designed based on iron-carbon micro-electrolysis treatment (ICME), physical adsorption (PA) with zeolite (Z) or vermiculite (V) and microalgae cultivation (MC, C. vulgaris) for removing pollutants from swine wastewater (SW), herein are ICME + MC (IM), ICME + Z + MC (IZM) and ICME + V + MC (IVM). Results showed that the minimum total nitrogen (TN) of 43.66 mg L−1, NH4+-N of 1.33 mg−1 and total phosphorus (TP) of 0.14 mg−1 were obtained by IVM, while the minimum chemical oxygen demand (COD) was 105 mg−1 via IM. During the process of combined treatments, ICME contributed most to the removal of TN (84.52% by IZM), TP (97.78% by IVM and IZM) and COD (62.44% by IVM), and maximum NH4+-N removal (55.64%) was obtained by MC procedure in IM process. Vermiculite performed better than zeolite during all the combined treatments. Besides, the maximum cell dry weight (CDW, 0.74 g−1) of C. vulgaris was obtained by IM on day 13. The results provide an efficient integrated method for swine wastewater treatment.

“…al. [20], la capacidad de intercambio catiónico depende de la densidad carga aniónica (sustitución de Al 3+ y Si 4+ ) de la estructura de la zeolita formada. Para el caso particular, la baja capacidad de intercambio catiónico se debe a la poca cristalinidad de zeolita Gis-NaP formada por transformación parcial de la fase amorfa (SiO2) a 100ºC [21].…”

El presente artículo reporta los resultados de una investigación efectuada a fin de obtener material zeolítico del tipo Gis-NaP con alta capacidad de intercambiar cationes utilizando residuos de ladrillos. La síntesis hidrotermal se realizó en un reactor de acero inoxidable utilizando soluciones activantes de NaOH a concentraciones de 2.0, 2.5 y 3.0 M, temperaturas de activación de 100, 120 y 140ºC y tiempos de activación de 7, 8 y 9 horas. El producto obtenido se caracterizó mediante, Fluorescencia de rayos X, Microscópico Electrónico de barrido (SEM), Difracción de rayos X, y la capacidad de intercambio catiónico (CIC). Los resultados obtenidos mostraron que para la prueba de conversión hidrotermal a la condición de 140°C/2M/7horas, se obtiene zeolita sintética Gis- NaP con una capacidad de intercambio catiónico igual a 163.5 meq/100g. El análisis estadístico aplicando un diseño experimental factorial, indicó que los principales factores con gran efecto sobre la capacidad de intercambio catiónico (CIC) son la temperatura de activación y la interacción entre ésta y la concentración de la solución activante, con un grado de significancia de 0.049250 y 0.056631 para un nivel de confianza de 90.82%. Se desarrolló un modelo matemático empírico y validado aplicando el análisis ANOVA que considera los efectos de interacción de todos los factores y que fue optimizado aplicando la metodología de superficie de respuesta.
