Malachite green dye and its removal from aqueous solution by clay-chitosane modified

Facile synthesis of CeO2 nanoparticles for enhanced removal of malachite green dye from an aqueous environment

“…11–17 Among these techniques, adsorption is more suitable due to its ease of operation, simplicity of design, effectiveness, high efficiency, and availability of a diverse range of adsorbents. 14,18–23 Accordingly, different adsorbents such as biomass, 16,17 activated carbon (AC), 24–26 clay composites, 27 and metal oxides and their composites 28–33 have been tested to remove malachite green dyes from water. Among different adsorbents, metal oxide nanoparticles have shown immense potential and outstanding performance as adsorbents due to their large surface area, porous structures, enormous active sites, thermal stability, ease of recovery, and low toxicity.…”

Bentonite Impregnation Ammonium-Assisted as Eco-Friendly Dye Adsorbent: Analyses of Kinetics and Thermodynamics in Cationic Dye Adsorption

“…The report on several works evidenced the surfactant cetyltrimethylammonium bromide (CTAB) intercalation to bentonite only provided the Qmax adsorption to rhodamine B dyes at 0.98 mg/g [14]. Other literature reported that bentonite modification by chitosan intercalation only achieved the Qmax adsorption to malachite green at 18.09 mg/g [15]. Furthermore, there is a lack of information on bentonite impregnation using ammonium as a single ion under low temperatures and time preparation.…”
