Glycidyl methacrylate-g-jute copolymer of an epoxy content of 0.529 mole/100g was aminated with any of cyclohexyl amine (CRA), hexyl amine(HA) or N-ethyl butyl amine (NEBA) at different factors, including amine concentration (0.08-8 mole/l), LR(1: 10-1:40), time (15-120 min.) and temperature(30-90°C). The extent of amination depends on the type of amine and it follows the order: CHA > NEBA > HA. At optimum conditions, viz. amine concentration of 5 mole/I, LR (1:20) for 15 min. at 90°C, 3 aminated jute fibers(AJF) were prepared, viz. CRAJF, HAJF and NEBAJF with % N of 5.92, 5.27 and 5.39% respectively. AJFs were used in the removal of Cu ions from aqueous solution at different pRs (2-8), CU2+ ion concentration (50-500 mg/l), AJF concentration (1-10 g/I), and time (15-180 min.). The extent of Cu ion removal depends on AJF type and follows the order: NEBAJF > CHAJF > HAJF. Optimal removal conditions at room temperature (30°C) were pR 5, Cu ion concentration 200 mg/l, adsorbent concentration 2g/1 and time of 180 min. The removal of Cu ions by the three different AJFs follows Langmuir and Freundlich isotherms.
