“…Recently, interest in the use of graphene-based materials such as methylene blue for water decontamination has increased, leveraging their large surface area and porous structure for efficient dye molecule adsorption, with removal efficiencies exceeding 95% [ 38 , 39 , 40 ]. Experimental and computational studies, including density functional theory (DFT) analyses, have been conducted to elucidate the adsorption capacity of MB on graphene, GO, and rGO, providing insights into the molecular adsorption mechanisms and predicting material adsorption capacities [ 41 , 42 , 43 , 44 , 45 , 46 ].…”

In this study, we analyzed the impact of hydroxyl and epoxy groups on the properties of graphene oxide (GO) for the adsorption of methylene blue (MB) dye from water, addressing the urgent need for effective water purification methods due to industrial pollution. Employing a dual approach, we integrated experimental techniques with theoretical modeling via density functional theory (DFT) to examine the atomic structure of GO and its adsorption capabilities. The methodology encompasses a series of experiments to evaluate the performance of GO in MB dye adsorption under different conditions, including differences in pH, dye concentration, reaction temperature, and contact time, providing a comprehensive view of its effectiveness. Theoretical DFT calculations provide insights into how hydroxyl and epoxy modifications alter the electronic properties of GO, improving adsorption efficiency. The results demonstrate a significant improvement in the dye adsorption capacity of GO, attributed to the interaction between the functional groups and MB molecules. This study not only confirms the potential of GO as a superior adsorbent for water treatment, but also contributes to the optimization of GO-based materials for environmental remediation, highlighting the synergy between experimental observations and theoretical predictions in advances in materials science to improve sustainability.

“…Pereskia grandifolia has high protein content with high digestibility, fiber, calcium, and iron (Almeida, Junqueira, Simão, & Corrêa, 2014;Almeida, Simão, Corrêa, & Fernandes, 2016). Opuntia ficus-indica has been used in food for its carbohydrates, proteins, fibers (for example, mucilage, cellulose, and pectin), calcium, iron and vitamin C (Loayza & Chávez, 2007;Silva et al, 2015;Figueirôa et al, 2021). Agave tequilana stands out for the minerals calcium, iron, magnesium, potassium, zinc and fibers (for example, cellulose, hemicellulose, and lignin) (Romero-López, Osorio-Díaz, Flores-Morales, Robledo, & Mora-Escobedo, 2015;Huerta-Cardoso, Durazo-Cardenas, Longhurts, Simms, & Encinas-Oropesa, 2020).…”

The aim of this study was to evaluate the morphometric parameters and the mass of adipose tissues of rats fed with cactacea flour. The animals were divided into five groups: C (Control), H (Hypercaloric diet), HP (Hypercaloric diet with 5% Pereskia grandifolia flour), HO (Hypercaloric diet with 5% Opuntia ficus-indica flour), and HA (Hypercaloric diet with 5% Agave tequilana flour). Feed intake and apparent digestibility, capillary glycemia, liver weight and Hepato-Somatic Index were evaluated. Adipose tissue mass and the Visceral Fat Index (VFI) and Epididymal Fat Index (EFI) were determined. The data were compared using the Tukey test at 5% significance level. There was no statistical difference between the groups for body weight, BMI and Lee Index. The HP and HA groups did not differ from the C group regarding weight gain, the C group had lower apparent digestibility of the diets, the HA group presented lower blood glucose when compared to the H and HO groups, and the H group had higher liver weight. The HP and HA groups gained the lowest adipose tissue mass, VFI and EFI than the H and HO groups. Among the cactaceae studied, Pereskia grandifolia showed better effects on morphometric and adipose tissue parameters.

Introducción: las permanentes descargas de efluentes sin tratamiento previo han aumentado de manera considerable en los últimos años propiciando la perdida de la calidad de los recursos hídricos lo que hace factible el desarrollo de sistemas de tratamiento de aguas para lo cual se utilizan productos químicos los cuales son dañinos para la salud por tal motivo se propone reemplazarlos en gran parte por agentes naturales derivados de productos vegetales que tengan un comportamiento similar o mejor a los mismos. Objetivo: Obtener un coagulante natural a partir de la hoja de Opuntia ficus indica (Tuna) mediante varias operaciones unitarias para el tratamiento de aguas residuales. Metodología: El coagulante natural descrito se obtiene a través de diferentes operaciones unitarias tales como: secado, molienda, tamizado y extracción sólido-líquido. Resultados: Se consiguieron muy buenos porcentajes de remoción como DQO 78,12 %, DBO5 58 %, Nitrógeno Total 89,06 %, Coliformes Fecales 100%, Coliformes Totales 100% y Turbidez 85,47 % evidenciando que el tratamiento es viable. Conclusión: Se comprobó que mediante la utilización de un coagulante natural extraído de la hoja de Opuntia ficus indica (tuna) se puede lograr porcentajes de remoción similares a los obtenidos por productos químicos convencionales atenuando considerablemente el nivel de contaminación en el producto final de dicho proceso. Área de estudio: Ingeniería Química e Ingeniería Ambiental.
