“…An appropriate knowledge of iron levels in both environmental waters and water for human consumption is very desirable. The relevancy of this subject has conducted to numerous reported methods using UV/Vis spectrophotometry [1][2][3][4][5][6][7][8][9][10][11][12], chemiluminescence [13][14][15][16][17], atomic absorption spectroscopy [18][19][20][21][22], and voltammetry [23,24]. The design and development of portable devices such as sensors rather than laboratory-based instruments in monitoring iron at trace levels in real samples is still of considerable interest.…”

Iron(II)-(1,10-phenanthroline) complex imprinted membrane was prepared by ionic imprinting technology. In the first step, Fe(II) established a coordination linkage with 1,10-phenanthroline and functional monomer 2-vinylpyridine (2-VP). Next, the complex was copolymerized with ethylene glycol dimethacrylate (EGDMA) as a crosslinker in the presence of benzoyl peroxide (BPO) as an initiator. Potentiometric chemical sensors were designed by dispersing the iron(II)-imprinted polymer particles in 2-nitrophenyloctyl ether (o-NPOE) plasticizer and then embedded in poly vinyl chloride (PVC) matrix. The sensors showed a Nernstian response for [Fe(phen)3]2+with limit of detection 3.15 ng mL−1and a Nernstian slope of 35.7 mV per decade.
