M. M. S. Sanad et al.

Summary: A simple and dry hybridization technique was utilized to fabricate a magnetic adsorbent for efficient removal of organic dyes. The adsorbent showed high adsorption capacity for crystal violet and acid red dyes, with Langmuir isotherm fitting well with the equilibrium data. Thermodynamic studies indicated that the adsorption process is spontaneous, endothermic, and favorable at high temperatures. The magnetic adsorbent demonstrated superior adsorption performance compared to activated bentonite for anionic dye removal, and similar performance for cationic dye removal, and could be easily reused and separated from textile wastewater with high removal efficiencies for both inorganic and organic pollutants.

The application of spent tyre activated carbons as low-cost environmental pollution adsorbents: A technical review

Isabelle Jones et al.

Summary: Spent tyre activated carbon (STAC) shows excellent performance in dye adsorption, heavy metal removal and flue gas cleaning, outperforming commercial activated carbon (CAC) in certain applications despite lower surface areas. STAC's enhanced performance is attributed to high mesoporosity, low surface pH, and acidic surface functional groups. Steam activated STAC has comparable results to CAC in terms of surface area and pore volume, making them cleaner and sustainable alternatives to conventional products.

Decoration of serpentine with iron ore as an efficient low-cost magnetic adsorbent for Cr (VI) removal from tannery wastewater

Mohsen M. Farahat et al.

Summary: In this study, a dry particle-particle coating technique was used to develop a magnetic adsorbent from natural mineral constituents, showing excellent removal performance for hexavalent chromium Cr(VI) as well as other heavy metals and organic contaminants. The synthesized composite displayed a maximum adsorption capacity of 138 mg/g and followed 1.2-order kinetics for Cr(VI) adsorption, with an exothermic nature. The composite (BIF@Serp) exhibited spontaneous adsorption behavior and was effective in treating real tannery effluent.
