This study introduces a merlinoite synthesized from sugarcane bagasse ash (SBA) and kaolin and evaluates its application as an adsorbent to remove lead from wastewater. The synthesis was performed via the hydrothermal method, and optimal conditions were determined. The adsorption of Pb by merlinoite was also optimized. Determination of the Pb2+ remaining in the aqueous solution was determined by atomic absorption spectroscopy (AAS). Adsorption isotherms were mainly studied using the Langmuir and Freundlich models. The Langmuir model showed the highest consistency for Pb adsorption on merlinoite, yielding a high correlation coefficient (R2) of 0.9997 and a maximum adsorption capacity (qmax) of 322.58 mg/g. The kinetics of the adsorption process were best described by a pseudo-second-order model. Thermodynamic studies carried out at different temperatures established that the adsorption reaction was spontaneous and endothermic. The results of this study show that merlinoite synthesized from kaolinite and SBA is an excellent candidate for utilization as a high-performance adsorbent for lead removal from wastewater.

“…On the other hand, the FTIR spectra also assert the structure of zeolite, characterized by the presence of intense bands at 477 -509 cm -1 that characterize the TO4 tetrhedral site (T=Al, T=Si). A 609 cm -1 peak characteristic of the outside of the double ring and bands at 738-680 cm -1 and 591-427 cm -1 attributed to the symmetrical elongation and bending vibrations of TO atoms respectively (Utami et al, 2019). The 1466-1476 cm -1 bands are assigned to the internal vibrations of the T-O-T tetrahedron and finally a 1638 cm -1 band characterizing the O-H bond of the water.…”

The aim of this paperis the synthesis of a Faujasite type zeolite: 9SiO2: Al2O3: 3Na2O: 120H2O and study its ability to remove heavy metals from an industrial effluent.Characterization of the zeolite was carried out by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM).The study of the elimination of ten heavy metalson anaqueous effluent, taken from the industrial zone of Bounoua(Algeria),showsthat the synthesized zeolite is able to eliminate nearly 40% of the analyzed heavy metals. the results demonstrate a removal rates of metals in a descreasing order, as following: Cd > Mn > Sn > Fe > Cr > Ni > Pb > Mg > Zn > Cu.Cadmium is the most adsorbed metal with a rate of86.47 % and copper takes the last position with a removal rate of19.27 %.The kinetics and isotherms study of adsorbtion of cadmiumby zeoliteshows that the adsorption is managed by kinetics of the pseudo-second order and the Langmuir isotherm represents better the adsorption of this metal.The study demonstrates that, besides the economy, zeolite facilitates the process of adsorbtion. Moreover, the zeolite is very efficient and reliable material to eliminate the heavy metals and to mitigate the problems of pollution of the environment causedby the industrial activities.

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.
