Preparation of an amino-modified biochar supported sulfide nanoscale zero-valent iron composite and its efficient removal of U(<scp>vi</scp>) from wastewater by adsorption and reduction

Abstract

A new amino-modified biochar supported sulfide nanoscale zero-valent iron composite (SnZVI–BC–NH 2 ) was prepared by a simple method, which removes uranyl ions efficiently through the synergistic effect of adsorption and reduction.
