Abstract
A novel membrane was created by utilizing a crosslinked Ti3C2Tx (MXene)/ethylenediamine (EDA) composite prepared through a hydrothermal method. The membrane exhibited remarkable properties, including high water flux (∼163.53 L m−2 h−1·bar−1, almost twice as much as the pristine MXene membrane) and excellent dye rejection, particularly for methylene blue (MB), with 100 % rejection in the first cycle. The N-Ti coordination bond formation was responsible for increasing the layer thickness of the membrane(pre-(6.4 µm) and post-(9.4 µm) modification), which improved dye selectivity. Notably, trivalent anions and cationic compounds had a significant impact on the water flux of the MXene-EDA membrane. The cationic compounds demonstrated a positive influence, while the anions had the opposite effect.
