Abstract

Novel method for polydopamine (PDA) modified biochar (BC) with immobilized NZVI.

PDA/NZVI@BC exhibits significantly enhanced activity for tetracycline (TC) removal.

TC removal efficiency was increased by 55.9% compared with that of pristine NZVI.

The mechanism of tetracycline removal by PDA/NZVI@BC was proposed.
