“…It is interesting that the polymerization of the monomers incorporated into the modified carbon paste electrodes described here produces cyclic voltammograms indicative of conducting polymers, a result that is in agreement with our previous work with 1,8-DAN involving electropolymerization of incorporated monomers [18]. A possible explanation lies in the juxtaposition of three phases where the paraffin oil here acts as an organic solvent for the electroactive monomers.…”

Carbon paste electrodes were modified by mixing appropriate amounts of the monomers o-phenylendiamine, pphenylendiamine and m-phenylendiamine (o-PD, p-PD and m-PD) into a graphite powder-paraffin oil matrix. The electropolymerization of the incorporated phenylendiamine was then carried out in a carbon paste electrode in acidic medium by cyclic voltammetry between À 0.30 V and þ 0.90 or under constant potential. The modified carbon paste electrodes (MCPEs) obtained by this electropolymerization method were found to be useful for trace determination of Pb 2þ in aqueous solutions. Lead(II) was first preconcentrated on the modified electrodes by complexation with the modifier, and the electrode was then transferred to an electrochemical cell. The best results in terms of sensitivity and detection limit were obtained with poly p-phenylenediamine (poly (p-PD)). For a 10-min preconcentration time, the calibration plot was linear from 5 Â 10, with r 2 ¼ 0.999 and relative standard deviation equal to 5%. However, the lowest lead concentration that could be detected was 10 À9 mol L À1 . Interference from metal ions like Cd(II), Hg(II), Zn(II), Fe(II) and Cu(II) was also studied.

“…In the last few years, aromatic polymers containing amine have attracted great interest of scientists due to their outstanding multifunctionality, involving adjustable conductivity, strong electroactivity, good optical and magnetic activity, colorful electrochromism, high thermal stability, and desired environmental applications [1,2]. Moreover, some aromatic diamine polymers have high sensitivity to certain metal ions, namely, Pb(II), Ag(I), Cu(II), Cr(III), and Hg(II), by means of redox reaction or chelation with the amino/ imino groups incorporated in the polymer chains [3,4]. Poly (1,8-diaminonaphthalene) fabricated via electropolymerization of 1,8-diaminonaphthalene has been utilized to sense and detect Pb(II) ions [3].…”

Copolymers of aniline and o-phenylenediamine/ kaolinite composites were synthesized by 5:1 molar ratios of the respective monomers with different percentages of nanoclay via modified in situ chemical co-polymerization. The results were verified by measuring the FT-IR and UVvis absorption spectra for PANI-o-PDA/kaolinite composites. The thermal behaviour of the copolymer and composites was studied. PANI-o-PDA/kaolinite composites were thermally more stable than pure copolymer. Surface morphology of copolymer composites was recorded at different magnification power by SEM which revealed whitish micrometric beads distributed all over the field with particle size in the range of 0.122-0.233 lm. This work demonstrates that the PANI-o-PDA/kaolinite composites particles can be considered as potential adsorbents for hazardous and toxic metal ions of water from lake ElManzala, Egypt. All of Cd(II), Cu(II), and Pb(II) posed dangerous health risk to the local population via fish consumption.
