Issue 5

Water and wastewater treatment and reuse

Electrochemical treatment of wastewater containing p-nitrophenol (PNP) was carried out using a platinum electrode as an anode and biochar-loaded nano zero-valent iron material as the cathode. The prepared biochar loaded nano zero valent iron electrode materials were characterized and analyzed using...
