Garlic peel based mesoporous carbon nanospheres for an effective removal of malachite green dye from aqueous solutions: Detailed isotherms and kinetics

Efficient cationic dye removal from water through Arachis hypogaea skin-derived carbon nanospheres: a rapid and sustainable approach

“…53 The following linear eqn (4) represents the Temkin isotherm model: 51 where b is the Temkin constant related to the heat of sorption (J mol −1 ), K T (L g −1 ) is the Temkin isotherm equilibrium binding constant, C e (mg L −1 ) is the concentration of dye molecules at equilibrium, q e (mg g −1 ) is the quantity of dye molecules removed at equilibrium, R is the universal gas constant (8.314 J mol −1 K −1 ), and T is the temperature (298 K). The constants are determined by plotting the quantity absorbed, q e vs. ln C e , 20,54 as shown in Fig. 6c and 7c for MB and MG, respectively, and the values obtained from the graph are tabulated in Table 2.…”

Recent progress in anion exchange membranes (AEMs) in water electrolysis: synthesis, physio-chemical analysis, properties, and applications

“…A wide range of materials for a variety of applications was developed, including silica, carbons, layered double hydroxide materials, perovskites, metal–organic frameworks, covalent organic frameworks, nanomaterials, zeolites, membranes, thin films, aerogels, xerogel, and clays, which were used for various applications such as energy, medicines, sensors, water treatment, solar cells, optoelectronics, and CO 2 conversion. 63–84 Among them, membranes are made of polymers, making them highly flexible, hydrophobic, high-performance, mass-produced, economical, and reliable for specific applications. 85–87 Accordingly, an anion exchange membrane (AEMs) is a semi-permeable membrane with ionic head groups attached to polymer substances.…”

Facile Fabrication of Layered Double Hydroxide-Lignin for Efficient Adsorption of Malachite Green

“…Adsorption has garnered the most attention among these due to its straightforward functioning, design flexibility, practical recyclability, and excellent reliability. For the purpose of removing MG from an aqueous solution, numerous sophisticated adsorption materials have been developed recently, including Costus woodsonii (Van Tran et al, 2022) , modified metal-organic frameworks (Dahlan et al, 2023) , biowaste garlic peel (Pathania et al, 2022) , and layered double hydroxide (Ahmad et al, 2023a) . Layered double hydroxides (LDHs) are a type of 2D anionic clay that is composed of layers (Nazir et al, 2022) .…”
