A new spongy adsorbent (PU-DTC) was prepared with a polyurethane (PU) adsorbent for removal of EDTA-Cu(Ⅱ) and EDTA-Ni(Ⅱ) from water. This new spongy adsorbent was characterized by using SEM and ¹³C NMR and FT-IR spectroscopy. Adsorption kinetic curve indicated that this new spongy adsorbent could quickly remove EDTA-Cu(Ⅱ) and EDTA-Ni(Ⅱ) from water, and adsorption isotherm also indicated that PU-DTC had high equilibrium adsorption capacity for EDTA-Cu(Ⅱ) and EDTA-Ni(Ⅱ).
