Environmental Friendly Synthetic Modification of Amberlite XAD-2 Resin for the Removal of Highly Toxic Hexavalent Chromium from Water
Amberlite XAD-2 functionalized by coupling through -C=N- spacer with isatin via an environmental friendly protocol. The modified resin was used for the evaluation of its sorption capacity towards toxic Cr (VI) ions using spectrophotometer. pH, volume, sorbent amount, initial concentration of Cr(VI)...

| description | Amberlite XAD-2 functionalized by coupling through -C=N- spacer with isatin via an environmental friendly protocol. The modified resin was used for the evaluation of its sorption capacity towards toxic Cr (VI) ions using spectrophotometer. pH, volume, sorbent amount, initial concentration of Cr(VI) ions, and agitation time were optimized. The Freundlich and Dubinin- Radushkevich models gave better fit to isotherm data than Langmuir model. The evaluation of kinetic data indicated pseudo-first-order kinetics followed by sorption process. Thermodynamic parameters were also evaluated. Maximum recovery was obtained at 10 mL of 0.1M NaOH. Spiking methodology was used to confirm the validity of proposed method. The results revealed that developed method can be used for the removal of Cr(VI) ions efficiently from water, as well as reused for three cycles. |
