Meso-structured and ladder organic–inorganic hybrid materials functionalized with ammonium carboxylate groups were prepared. These materials were obtained by the sol–gel process starting from the cyanopropyltriethoxysilane precursor as a building block. Hydrolysis of CN to COOH groups followed by treatment with triethylamine gives rise to cationic exchange materials. These materials exhibit a high chelating capability towards cations and can be used for water treatment. Lead ion (Pb2+) was tested as example; and, some tests were made on the meso-structured and ladder material for further comparison in efficacy of extractions.
This research was presented at the 20th Lebanese Association for the Advancement of Science (LAAS) International Science Conference, held in the Lebanese University in March 2014.
