Japanese researchers turn waste bulrush into copper material for dye removal
Researchers at Doshisha University in Japan have developed a method to convert waste bulrush into a copper-enhanced adsorbent for removing synthetic dyes from wastewater.
New adsorbent removes toxic dyes
Industrial activities such as textile manufacturing and paper production generate wastewater containing synthetic dyes that are chemically stable and difficult to biodegrade. These persistent contaminants pose risks to aquatic ecosystems and human health when released into waterways. The team devised a single-step co-pyrolysis strategy to transform agricultural waste into an amphoteric adsorbent capable of capturing these pollutants.
Study details and publication
Asif Ali, a Ph.D. student and MEXT scholar, led the project alongside professors Michiaki Matsumoto and Yoshiro Tahara from the university's Department of Applied Chemistry. Their findings regarding this new treatment approach appear in the Journal of Environmental Chemical Engineering. The study addresses the lack of a universally suitable wastewater treatment method for such persistent contaminants.
