The new hyper cross-linked chelating resin NDWJN2 modified with carboxyl groups was prepared for removal of Cu²⁺ and Ni²⁺ from water. NDWJN2 was characterized using BET, SEM and FT-IR spectroscopy. Comparing with commercial resins D113 and IRC84, NDWJN2 could remove Cu²⁺ and Ni²⁺ from water more effectively. Langmuir model could fit adsorption isotherms well.
