Overview

Experimental study demonstrates rapid UVC-hydrogen peroxide degradation of pharmaceuticals in reverse osmosis concentrate, highlighting the decisive impact of water matrix composition.

Key Points

  • Investigate the efficiency and matrix-driven effects of UVC/H2O2 photoperoxidation on the degradation of six pharmaceuticals in reverse osmosis concentrate and other aqueous matrices.
  • Assessed the degradation kinetics of six pharmaceuticals (acetaminophen, caffeine, naproxen, progesterone, sulfathiazole, and testosterone) using UVA photolysis, UVC irradiation, and UVC/H2O2 treatment.
  • Compared process performance across diverse water matrices, including ultrapure water, reverse osmosis concentrate, post-membrane bioreactor effluent, and surface water containing varying concentrations of humic acid.
  • Optimized UVC/H2O2 conditions (0.87 mmol L⁻¹) degraded all six pharmaceuticals within 40 minutes in ultrapure water and within 30 minutes in reverse osmosis concentrate.
  • High dissolved organic matter content and elevated humic acid inhibited degradation via UV light attenuation and radical scavenging, whereas low humic acid concentrations accelerated degradation.
  • Naproxen was the least persistent compound across treatments, whereas acetaminophen was the most persistent.
