| dc.description | A new poly(vinyl chloride) membrane electrode that is highly selective to Fe3+ions was prepared by using 4,4'-Dimethoxybenzil bisthiosemicarbazone (DBTS) as a suitable neutral carrier. Membrane incorporating 4,4'-Dimethoxybenzil bisthiosemicarbazone (DBTS), as ionophore with composition DBTS :NaTPB:NB:PVC in the ratio 2:2:64:32 (w/w) exhibits the best result for potentiometric sensing of Fe3+ ions. The electrode exhibited a near-Nernstian response to Fe3+ in the concentration range of 1.0 x 10-6to 1.0x10-2M with a slope of 19.4 ± 0.5 mV per decade. The proposed sensor can be used over a period of 2 months. The lower limit of detection was 3.6x 10-7 M. This electrode showed high selectivity with respect to alkaline, alkaline earth, and heavy metal ions and could be used over a pH range of 1.8-5.0. It has been successfully used as an indicator electrode in potentiometric titration of Fe3+ against EDTA as well as for the determination of Fe3+ in water sample solutions (tap and mineral water samples). | |
