文摘

A novel ultra-fine natural zeolite supported Fe-Ni composite was synthesized. The catalytic ability and stability of Z-nZVI-Ni increased significantly. Z-nZVI-Ni demonstrated remarkable performance for TCE degradation. The hydroxyl radicals (OH) played the dominant role in TCE degradation. The slow leaching of Fe and Ni presented its extended stability.
