In this study, a high-efficiency magnetic heavy metal flocculant [email protected]
was prepared based on carboxymethyl chitosan and magnetic Fe3
. It was characterized by SEM, FTIR, XPS, XRD and VSM, and the Cu(II) removal rate was used as the evaluation basis for the preparation process. The effects of AMPS content, total monomer concentration, photoinitiator concentration and reaction time on the performance of [email protected]
flocculation to remove Cu(II) were studied. The characterization results show that [email protected]
has been successfully prepared and exhibits good magnetic induction characteristics. The synthesis results show that under the conditions of 10% AMPS content, 35% total monomer concentration, 0.04% photoinitiator concentration, and 1.5 h reaction time, the best yield of [email protected]
is 77.69%. The best removal rate is 87.65%. In addition, the response surface optimization of the synthesis process of [email protected]
was performed. The optimal synthesis ratio was finally determined as iron content 6.5%, CMFS: 29.5%, AM: 53.9%, AMPS: 10.1%. High-efficiency magnetic heavy metal flocculant [email protected]
shows excellent flocculation performance in removing Cu(II). This research provides guidance and ideas for the development of efficient and low-cost flocculation technology to remove Cu(II) in wastewater.
