“…Therefore developing a method to sensitively and selectively detect Al 3þ is crucial. In the recent years, various methodologies for metal ion detection have been reported based on potentiometric [6e8], colorimetric [9e11], fluorescence [12e14], liquid chromatography [15], inductively coupled plasma-atomic emission spectrometry (ICP-AES) [16], atomic absorption spectrometry (AAS) [17] [24], poly(phenylene ethylene) (PPE) [25], polydiacetylene (PDA) [26], polythiophene (PT) [27,28] and polyfluorene (PF) [29] have been widely reported as a colorimetric or fluorescence chemosensors. However, most reported conjugated polymers exhibit rather poor solubility in water probably due to their low charge densities which compete with the aromatic pep stacking of the hydrophobic backbones [30].…”

A colorimetric Al3+ sensor based on fluorescence recovery of a conjugated copolymer-ATP complex is proposed. An optimized ratio of two polythiophene (PT) monomers is utilized to synthesize copolymer (CP) that yielded maximized colorimetric response for Al3+ in deionized (DI) and tap water. The electrostatic disassembly of CP-ATP upon addition of Al3+ led to an evident visual color change. The lowest concentration of Al3+ for naked eye observation is around 4 μM, which is below the threshold levels in drinking water according to European Economic Community (EEC) standard. Besides, the proposed assay showed a similar response to Al3+ in tap water. The proposed methodology showed selective and sensitive detection for Al3+ in analytically relevant concentration ranges without involving sophisticated instrumentation, illustrating the applicability for on-site drinking water monitoring.MOE (RG 82/12); Provost Office Nanyang Technological University, Singapor

“…[3][4][5][6] As a result of its widespread use, aluminum is present in various environment samples where its determination becomes important in view of its toxic effects. Although a number of methods such as spectrophotometry, 7 spectrofluorimetry, 8 graphite furnace atomic absorption spectrometry (GF-AAS), 9 inductively coupled plasma atomic emission spectrometry (ICP-AES) 10 and high performance liquid chromatography (HPLC) 11 have been reported for determination aluminum in samples, their applications are restricted due to the complicated process of operating or expensive instrumentation.…”

A highly selective PVC membrane electrode for Al 3+ based on salicylaldehyde salicyloyl hydrazone as a neutral carrier has been prepared and studied. The sensor exhibits a good response for Al 3+ over a linear range of 9.0 × 10 -6 to 1.0 × 10 -1 mol/L, with a Nernstian slope of 20.0 ± 0.2 mV/decade and detection limit of 7.0 × 10 -6 mol/L. Selectivity coefficients determined by the method of separate solution indicate high selectivity for Al 3+ . The response mechanism was discussed in view of UV-Vis spectroscopy technique and the A.C. impedance technique. It was used as an indicator electrode in potentiometric titration of Al 3+ with EDTA and in the determination of Al 3+ in real samples. The electrode has a relatively fast response time, long life time and satisfactory stability.

“…The problem of determination of trace quantities of aluminum has engaged the attention of chemists for many years. The most commonly used technique for the determination of trace level of aluminum is atomic absorption spectroscopy AAS [5][6][7], inductively coupled plasma (ICP) [8], flow injection chromatography [9,10] and spectrofluorimetry [11,12].…”

“…Recently a few AdSV procedures have been reported for the determination of aluminum using different complexation agents such as: 1,2-dihydroxyantraquinone-3-sulfonic acid (DASA) [17,25,26], cupferron [18,19,22], solochrome violet R S [20], arsenazoIII [21], quinolin-8-ol [23], alizarin S [24] and oxine [27]. However, the reported methods suffer from limitations such as interferences from commonly associated ions [21,23,[25][26][27], high limit of detection [5,10] narrow linear range [8,10] and long accumulation time [6]. The aim of this study is to obtain sensitive, selective and simple method for determination of aluminum ions based on differential pulse cathodic adsorptive stripping voltammetry in the present of dithiooxamide.…”

Quantification of Sub‐Nanomolar Levels of Aluminum by Adsorptive Stripping Voltammetry Using Rubeanic Acid as a Selective Chelating Agent

A novel, sensitive and selective adsorptive stripping procedure for determination of aluminum is presented. The method is based on the adsorptive accumulation of dithiooxamide (Rubeanic acid) complex of aluminum onto a hanging mercury drop electrode, followed by reduction of adsorbed species by voltammetric scan using differential pulse modulation. The influences of control variables on the sensitivity of the proposed method for the determination of aluminum were studied. The optimum analytical conditions were found to be Rubeanic acid (RA) concentration of 8.0 10 À5 M, ammonia buffer (NH 3 ÀNH 4 Cl) pH of 6.5, and accumulation potential at À50 mV vs. Ag/ AgCl with an accumulation time of 60 s. The peak currents are proportional to the concentration of aluminum over the 0.3-70 ng mL À1 ranges with detection limit of 0.012 ng mL À1. The procedure was applied to the determination of aluminum in the Lab. Water, HCl of Merck and potato samples with satisfactory results.
