To develop a biodegradable, porous bamboo fiber demulsifier via surface grafting and evaluate its performance in separating emulsified oily wastewater under varied environmental conditions.
Synthesized functionalized bamboo fibers (F-BF) by pretreating natural bamboo fibers and grafting polyethylenimine onto their surface using a Schiff base reaction.
Evaluated demulsification efficiency across variations in oil concentration, demulsifier dosage, pH (4.0–10.0), temperature (up to 80 °C), and salinity (0–2.0 wt % NaCl), alongside reusability over 5 cycles.
Achieved maximum demulsification efficiencies of 97.4% at pH 4.0, 95.2% at pH 7.0, and 86.5% at pH 10.0, with efficiency decreasing as oil concentration increased.
Observed increased demulsification efficiency reaching 98.2% at 80 °C and rising from 96.8% to 99.2% as NaCl concentration increased from 0 to 2.0 wt %.
Retained superior demulsification performance across 5 consecutive reuse cycles, driven by positive surface charge, high interfacial activity, and lignin interactions.
