Dye wastewater treatment

Doshisha chemists use bulrush's own gases to load copper into a dye-removing carbon

Doshisha University chemists used one heating step to turn waste bulrush into a copper-laced carbon that took up as much as 62 mg of dye per gram. The lab results support a low-cost dye adsorbent for textile wastewater, though no test on real effluent has been reported.
