Synthesis and characterization of montmorillonite – Mixed metal oxide composite and its adsorption performance for anionic and cationic dyes removal

Upcycling of sugar refining mud solid waste as a novel adsorbent for removing methylene blue and Congo red from wastewater

“…Two dye stock solutions of 1000 ppm were prepared in distilled water. Experimental solutions of 10,25,50,75,100,125,150,175,200,225 and 250 ppm were obtained through serial dilutions.…”

“…15,17 Previous studies have explicitly focused on MB and CR, highlighting the effectiveness and potential of different adsorbents as remediation agents for these dyes. 8,10,[18][19][20][21] However, some common challenges related to producing adsorbents are high production and operational costs as well as the degradation and non-reusability of adsorbents. 22 In this work, we attempt to address some of these problems by utilizing sugar rening MSW, an agro-industrial waste produced in signicant amounts during the sugar rening process from sugar beets and poses adverse environmental effects, as a novel costeffective and environmentally friendly alternative for removing these dyes from water.…”

“…For example, hydrogel polymers, metal oxides, composites, layered double hydroxides, and treated biosorbents are among the materials being studied for their efficient adsorption of dyes from water, a topic that has gathered significant recent attention and is the focus of this work. 6–10…”

Indoor Air Quality Treatment Using Polymer Nanocomposite Adsorbents

“…Efficiency of adsorbents for indoor air purification depends on the adsorption capacity of the material used, which is directly affected by their surface area [23][24][25]. Recently, polymers and polymeric nanocomposites have been researched as low-cost promising adsorbents for indoor pollutants [26].…”

Modified Layered Double Hydroxide Mg/M3+ (M3+ = Al and Cr) Using Metal Oxide (Cu) as Adsorbent for Methyl Orange and Methyl Red Dyes

“…Research conducted by Taher et al [17], a composite material based on montmorillonite-mixed metal oxides derived from ZnAl-LDH resulted in an adsorption capacity of 40 mg/g on the Congo Red dyes adsorption. Kumar et al [18] said that ZnO and SnO 2 can remove malachite green oxalate dye with a maximum adsorption capacity of 310.50 mg/g and 216.90 mg/g.…”
