文摘
- •
A novel composite of humus/nanoscale zero-valent iron was prepared.
- •
High efficiency removal of Cr(VI) resulted from the composite of H-NZVI.
- •
Cations greatly facilitated the removal of Cr(VI), and the effect of Mg2+ was extraordinary.
- •
The removal mechanism of Cr(VI) consisted of physical adsorption and reduction.
