以聚氨酯（PU）为吸附剂，制备了一种新型海绵状吸附剂（PU-DTC），用于去除水中的EDTA-Cu（II）和EDTA-Ni（II）。用扫描电镜、13 C NMR和FT-IR对吸附剂进行了表征。吸附动力学曲线表明，该新型海绵状吸附剂能快速去除水中的EDTA-Cu（II）和EDTA-Ni（II），吸附等温线表明，PU-DTC对EDTA-Cu（II）和EDTA-Ni（II）具有较高的平衡吸附容量。
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 and13C 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).
