Synthesis and characterization of azide-functionalized particles for removing metal ions in wastewater |
| 초록 |
In this study, we synthesized GAP-based particles contain functional azide groups on the surface as a polymeric adsorbent applied to remove metal ions. The stable particles were prepared by suspension method. Glycidyl azide polymer was crosslinked by bis-propargyl succinate via Cu-free Click reaction. Effect of suspension parameters were studied on particle size and partilce size distribution to provide control size of particles. The presence of azide groups on particles was showed at 2097 cm-1 through FTIR result and its spherical morphology was observed by microscope measurement with different sizes from 0.25-1.4mm. TGA results showed high thermal stability of particles through high decomposition temperature at 240oC. Adsorption experiment was studied on Hg(II), Pb(II) metal ions. Freundlich isotherm model was used to describe the heterogeneous adsorption between particles and Pb(II) while Linear isotherm model predicted the adsorption process for Hg(II). |
