Application research on the adsorption of Cu2+ ions in wastewater by hydroxyl‐ or amino‐terminated polyamines

Abstract The adsorption properties of hydroxyl‐ or amino‐terminated polyamines for Cu2+ ions are studied in detail by adopting the batch method, and the effects of main imprinting conditions, such as the concentrations of Cu2+ ions, temperature, pH and the amount of N are examined. The results showe...
