Ultrasonic-assisted synthesis of zeolite/activated carbon@MnO2 composite as a novel adsorbent for treatment of wastewater containing methylene blue and brilliant blue

Synthesis of activated carbon composited with Egyptian black sand for enhanced adsorption performance toward methylene blue dye

“…On the other hand, the higher adsorption percentage of MB onto garnet (GA) adsorbent was 44% at 308 K, and this percentage slowly decreased by raising the temperature to 323 K to be 32% 86 . This behavior might be caused by the MB dye molecule's motions and colliding more quickly when rising temperature and may decrease the adsorptive forces between the dye species and the active sites on the adsorbent surface which reduces the removal efficiency 86,87 .…”

“…Worthy mention that, the negative values of entropy (ΔS•) for MB dye onto (GA), (OS400) and (OSMG) explained the irregularity at the interface of the solid/solution decreases and a less chaotic condition of the adsorbed MB ions on the adsorbent [85,99]…”

“…In order to determine the kind of adsorption between the adsorbents and MB dye solution [86]. In this study the equilibrium sorption data were analyzed using linearized versions of Freundlich and Langmuir isotherms equations (3&4) [85,87].…”

Study on MoS2/Fe‐MIL‐88NH2 Transition metal dichalcogenide/Metal‐organic framework as a novel composite for highly adsorption of methylene blue dye from aqueous solutions

“…[ 10 ] In recent years, absorption technologies have attracted considerable attention for removing paint from industrial sectors due to their low costs, single‐step operation, simple design, environmental friendliness, economic feasibility, and high efficiency. Until now, purification, such as activated carbon [ 11 ] or zeolite, [ 12 ] banana and lemon peel, [ 13 ] polymer resins, [ 14 ] silica nanoparticles, [ 15 ] graphene, [ 16 ] clay, and metal–organic frameworks (MOFs) have received substantial interest as an adsorbent in the adsorption field. [ 17 ] In recent years, researchers have been increasingly interested in MOFs, which possess ultra‐high porosity, porous volume, and topological structure enrichment.…”
