Herein, polyethyleneimine (PEI) and carbon disulfide (CS 2) co-grafted magnetic lignosulfonate (LS) with magnetism (PEI/CS 2@ MLS MW) was synthesized through microwave-assisted synthesis technology and was employed for treating the water contaminated with Pb (II)/Cr (VI). Characterization results proved the modification substances were successfully loaded onto adsorbent, and the introduction of formaldehyde (HCHO) further enhanced PEI binding on PEI/CS 2@ MLS MW via Mannich reaction …
