| Abstract: | A new hybrid adsorbent based on zeolite modified with hyperbranched polyesterpolybenzoylthiocarbamate is presented. The structure and morphology of the sorbent are characterized by potentiometric titration, IR, 1H and 13C NMR spectroscopy, and electron microscopy. The fundamental possibility of extracting transition metal ions has been demonstrated using the examples of CuII and CoII ions. It is shown that the sorption capacity of the adsorbent to CuII salt is 25.34 mg g?1. A method of sorbent regeneration is proposed. |
