Preparation of new hyper cross-linked chelating resin for adsorption of Cu2+ and Ni2+ from water

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.
