Özet:

 

Cationic hydrogels from a positively charged monomer,  (3-Acrylamidopropyl)-trimethylammonium chloride (APTMACl), were  synthesized as bulk, and micro- and nano-sizes.  These hydrogels were  utilized to remove contaminants such as food dyes and an  environmentally toxic metal, arsenic.  The micro- and nanohydrogels  were dispersed in another hydrogel network to design a  semi-interpenetrating network (semi-IPN) which was shown to visualize  the particles that can be used for absorption purposes.  The  micron-sized cationic hydrogel particles were very effective in the  removal of arsenic from an aqueous environment- 96% of the arsenic  was removed in less than 10 min from a 55-ppm aqueous stock solution.   Cationic hydrogels ca.  5 nm were also prepared and demonstrated for  fluorescein dye absorption in the nanohydrogel-hydrogel semi-IPN.  Hydrogel particle sizes were investigated with microscopic methods,  such as optical, fluorescence, scanning electron and transmission  electron microcopes.
