Synthesis, characterization, ion-exchange and antimicrobial study of poly[(2-hydroxy-4-butoxy benzophenone)ethylene] resin and its polychelates with lanthanides

摘要

The polymeric ligand (resin) was prepared from 2-hydroxy-4-butoxy benzophenone with ethane diol with polyphosphoric acid as catalyst on constant heating at 160°C for 13 h. The poly[(2-hydroxy-4-butoxy benzophenone)ethylene] (HBBP-ED) forms 1 : 2 metal : ligand polychelates with La(III), Pr(III), Nd(III), Sm(III), Gd(III), Tb(III) and Dy(III). The polymeric ligand and its polychelates were characterized by elemental analyses, electronic spectra, magnetic susceptibilities, IR-spectroscopy, NMR and thermogravimetric analyses. The molecular weight was determined using number average molecular weight (M n) by a vapor pressure osmometry (VPO) method. All the polychelates are paramagnetic except La(III). Ion-exchange studies at different electrolyte concentrations, pH and rate have been carried out for the lanthanide ions. The resin can be used as an ion-exchanger and antimicrobial agent.View full textDownload full textKeywordsPoly[(2-hydroxy-4-butoxy benzophenone)ethylene], Lanthanide(III) polychelates, Thermal study, Ion-exchange, Antimicrobial studyRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00958970701391290
