Description
Ammarah Mushtaq and co-authors test treated peanut husks for cleaning dye from water in this 2026 study. Peanut husks are farm waste; soaking them in oxalic acid turns them into a sponge for a bright red dye used in labs and industry. The team ran batch tests to find the best mix of acidity, dose, time, heat, and stirring.
At the best settings, each gram of husk held about thirty-one milligrams of dye. The uptake followed a pattern tied to surface filling, and the process drew in heat yet ran on its own once started. A common acid washed out eighty percent of the dye for reuse, and the husks kept most of their power over three cycles. The authors pitch the method as a cheap, green route for dye waste.
