Overview

Randomized trial investigates the effectiveness of hydrogen plasma-derived slag for phosphate removal, suggesting a use for metallurgical waste.

Key Points

  • This research aims to assess the feasibility of using hydrogen plasma-derived slag for efficient phosphate removal from water.
  • Conducted batch adsorption experiments to determine phosphate removal efficiency under varying conditions.
  • Evaluated the effects of contact time, solution pH, sorbent dosage, and initial phosphate concentration.
  • Measured phosphate concentrations using the ammonium molybdate method.
  • Achieved up to 90% phosphate removal efficiency at optimal conditions.
  • Maximum adsorption occurred at an acidic pH of approximately 2.
  • Adsorption equilibrium was reached after about 18 hours of contact time.
