Abstract

The article studies the synthesis of a complex sorbent based on urea-formaldehyde resins modified with reagents containing nitrogen and oxygen. The exchange capacity of Zn (II), Ni (II), Cu (II) ions has been established for some d-metals of the sorbent forming a complex. Based on the results of IR spectroscopic and thermal studies, the structure of the obtained sorbent is proposed.
