Removal of Aqueous Heavy Metal Ions by Hyperbranched Poly(amide dihydrazide) Particles |
| 초록 |
Poly(amidoamine)s (PAMAM) are powerful sorbents for heavy metal ions in water due to their abundant N-functionalities and high binding affinity. We synthesized and analyzed poly(amide hydrazide) (PAMH) hydrogel particles that resembles PAMAM polymers in their chemical structure. In Cd2+ and Cu2+ ion sorption tests, the synthesized PAMH hydrogel particles exhibited maximum sorption capacity of 85 mg/g for Copper (II) and 47 mg/g for Cadmium (II). Interestingly, the PAMH showed improved sorption ability in acidic condition (only 10% decrease compared to neutral condition) in contrast to the diamine-based hyperbranched PAMAM that showed ~90% decrease of sorption ability at pH of 4. |
