“…A lo largo de los años se han denotado la gran cantidad de usos que puede llegar a tener el carbón activado por sus propiedades fisicoquímicas que le confieren su alta capacidad de adsorción, que permiten su aplicación en la rama industrial, cosmética y farmacéutica. Por esta razón se han evaluado diferentes precursores con fin de disminuir los costos referentes a la producción de este, buscando materiales con alto contenido de carbono, bajo índice de degradación en el almacenamiento y de fácil acceso, enfocándose en residuos agroindustriales como lo son la cascarilla de arroz (Le Van & Luong Thi, 2014), semilla de oliva (Ramirez et al, 2007), pino pátula (Cubides & Ramírez, 2014), residuos de café (Ramírez et al, 2013), cuesco de palma (Alvarez, 2019), semillas de higuerilla (Ferreira et al, 2020) y la cascara de coco (Gratuito et al, 2008).…”

“…PAC has pore size distributions that span a wide range and includes narrow mesopores as well as wider micropores. Since micropores have a signi cant impact on the adsorption of small molecules, such porosity is suitable for adsorption (Ferreira et al 2022). Figure 4(b) depicts BJH analysis where the pore size distribution was studied concerning the differential volume.…”

This study investigated the performance of the sequential electrocoagulation process (ECP) combined with the adsorption phenomena (AP) by powdered activated carbon (PAC) is a highly effective and environmentally friendly method of treating textile e uents. The discharge of textile e uent into any stream would affect the growth of living organisms and the environment due to its increased colour and total organic carbon (TOC). This scienti c work ease out the removal of toxic textile industry e uents such as high concentrations of colour and TOC by using the synthesized CaCl 2 -powdered activated carbon (PAC) derived from coconut shells combined with ECP (ECP-PAC). Initially, PAC was characterized by FE-SEM, XRD, Raman, BET, FTIR, and TGA studies. Subsequently, the pilot scale ECP batch reactor was designed and constructed with iron (Fe) as an anode and copper (Cu) as a cathode combined with the PAC adsorption process (5g/L of PAC and 30 min). Importantly, the combination of ECP-PAC has achieved a higher degree of treatment e ciency in shorter reaction time with lower energy consumption as compared to the ECP. i.e., 15 min duration was required to degrade 98% of the colour content of industrial textile e uent, and 30 min duration was required to reduce the higher concentration of TOC level of 96%. Moreover, the other parameters in the ECP or ECP-PAC such as pH (6-9), current density (0-50 mA/cm 2 ), time (0-30 min), electrode combinations (Fe-Cu), and so on were optimized.Finally, to understand the physicochemical properties of the treated water, seed germination of mung bean and chlorophyll content tests were convincingly carried out. Accordingly, tests on the seed germination of mung beans and chlorophyll contents tests have revealed that the ECP-PAC treated water is appropriate for irrigation. Thus, the methodology of treating textile e uent could have been an effective strategy for decreasing freshwater consumption in agricultural areas and increasing water availability in areas of water shortages.

“…The chemical activation has been chosen because of its advantages over physical activation, including a higher surface area, a comparatively shorter preparation time, and a higher product yield (Jawad et al 2021). Several experiments have been carried out to examine new efficient chemically activated carbons (Ferreira et al 2020;Giraldo et al 2021;Wang et al 2021;de Souza et al 2022).…”
