Overview

This research demonstrates hydroxyapatite's capacity to significantly reduce copper levels in water, indicating a promising solution for metal contamination.

Key Points

  • Hydroxyapatite effectively removes copper ions from water, achieving significant reduction at optimal conditions.
  • Maximum removal efficiency for copper was noted at pH of 5.5 and a contact time of 350 minutes.
  • The study designed and tested a treatment unit capable of purifying over 1000 liters of water contaminated with copper.
  • Initial copper concentrations of 4 mg/L and 6 mg/L were successfully treated using specially constructed prototypes.
