ClearA Symmetry Concept for the Self-Assembly Synthesis of Mn-MIL-100 Using a Capping Agent and Its Adsorption Performance with Methylene Blue

Rapid adsorptive removal of eosin yellow and methyl orange using zeolite Y
Researchers synthesized zeolite Y using an energy-efficient method that recycles waste heat from a chemical reaction instead of external heating, then tested it as an adsorbent to remove two industrial dyes from water.

Study on the adsorption properties of organically modified diatomite for methylene blue
Researchers created a new eco-friendly composite material made from diatomite (a natural sediment), chitosan, and alginate that can adsorb the toxic textile dye methylene blue from water with a capacity of nearly 550 mg per gram — outperforming many conventional materials. The adsorbent requires no harsh chemical crosslinkers and works best under mildly alkaline conditions, making it a low-cost, sustainable option for industrial wastewater treatment.
