Description
Priya Pal and co-authors compare raw orange peel powder with two chars made from it for removing crystal violet dye in a 2026 study. Fruit waste could serve water treatment if it binds dye well.
Peel powder hit a top uptake of 49.35 mg per g, far above the muffle furnace char at 19.05 and the nitrogen char at 12.87 mg per g. Rich surface groups on the raw peel explain the lead. The chars traded capacity for wider pH tolerance and steadier behavior. All three followed monolayer binding with chemistry-led speed. Peel uptake released heat and ran on its own at room temperature, while the chars preferred warmth.
