Hollow carbon fibers and flakes derived from Calotropis procera as adsorbents for dye removal from aqueous solutions

Highly efficient and reusable polymeric nanofibers for cationic dye removal: isotherm, kinetics and thermodynamic study

“…7 However, because of its low cost, simplicity of use, absence of secondary contaminants, and abundance of adsorbent materials, adsorption has emerged as the most successful and promising technique. 8 The adsorbent is indeed a critical component of the adsorption process, and its cost is a significant factor in the overall cost of the process. 9 Adsorbents of various kinds, such as activated carbon, mineral oxides, resins, and biosorbents, have been used to remove and recover organic contaminants from wastewater.…”

Single-step pyrolysis of biomass waste-derived activated carbon encapsulated zero-valent nickel NPs for the purification of antibiotic-contaminated water

“…25 Physical activation and chemical activation (e.g., using acids or alkalis) are two methods for producing AC. 26,27 In a study conducted by Ahmed et al, 28 activated carbon (AC) was prepared using a microwave technique with two different activation agents: KOH and K 2 CO 3 . The study findings demonstrated that the surface area of the AC was influenced by the type of activating agent employed.…”

Activated Carbon-Incorporated Tragacanth Gum Hydrogel Biocomposite: A Promising Adsorbent for Crystal Violet Dye Removal from Aqueous Solutions

“…Recent advances in water treatment research have yielded a variety of effective techniques for removing organic dyes, but these techniques vary in terms of cost, efficiency, and the potential to generate secondary pollutants [9,10]. Because of its efficiency and versatility, the adsorption technique has attracted a lot of attention among other approaches [11]. Adsorption is the attachment of dye molecules to the surface of solid materials, which effectively reduces their concentration in water.…”
