Description
Mohamed A. Hassaan and colleagues published a 2026 study turning red algae into a dye-cleaning material. The team converted the seaweed Pterocladia capillacea into biochar, then treated it with ammonia to add nitrogen-rich surface groups. They tested the product against three common industrial dyes in water: Acid Yellow 36, Methyl Red, and Methylene Blue.
Laboratory characterization confirmed the new surface chemistry and better heat stability than untreated biochar. In batch tests, uptake followed a monolayer model, with the highest capacity, over eight hundred milligrams per gram, for Methylene Blue. Uptake speed fit a chemical-adsorption pattern, and the material could be regenerated for reuse. A neural network model helped predict performance. The authors present the algae char as a low-cost option for dye wastewater.
