“…Nevertheless, the excessive ingestion of aluminum can influence negatively the human organism disturbing calcium and phosphate metabolisms and thus damaging the bone system. Moreover, the accumulation of high amounts of aluminum in the brain is associated to Alzheimer disease, senescence symptoms and amnesia of young people [2]. Human beings are exposed to aluminum from several sources such as atmospheric air, cosmetics, foods, drinking water and medicines.…”

2-(3-indolyl) -4,5 di phynyl imidazole(IDPI), was used as a complexing agent in cloud point extraction for the first time and applied for selective pre-concentration of trace amounts of Aluminium. The method is based on the extraction of Aluminium at pH 3.5 by using nonionic surfactant T-X114 and 2-(3-indolyl) -4,5 di phenyl imidazole.(IDPI) as a chelating agent. The adopted concentrations for IDPI, Triton X-114 and HNO3, bath temperature, centrifuge rate and time were optimized. Linearity for Al was obeyed in the range of Al 3+ ion 0.2-20.0 ng mL -1 . The Detection Limit (n=10) 0.013(µg.mL -1 ) for Aluminium ion, and along with enrichment factor of 37 for Aluminium ion, RSD % (n=5) 1.3(µg.mL -1 ) for Aluminium ion was achieved. The high efficiency of cloud point extraction to carry out the determination of analytes in complex matrices was demonstrated. The proposed method was successfully applied to the ultra-trace determination of aluminium in real samples.

“…The direct determination of Zr (IV) in alloy and other samples is of great importance in analytical point of view. There are numerous methods outlined for determination of Zr (IV) in literature [3][4][5][6][7][8][9]. Trace amounts of zirconium have been determined by X-ray fluorescence, neutron activation, atomic emission and spectrophotometry (10)(11)(12)(13)(14)(15) .…”

“…Spectrophotometric methods occupy special position due to their simplicity, less expensive instrumentation and high sensitivity. Many methods of zirconium determination have been published [1,[3][4][5][6][14][15][16][17]. However, some of these methods have both low sensitivity and low selectivity while others have high sensitivity but low selectivity in presence of some ions or molecules.…”

A rapid, simple, selective, and sensitive method for trace determination of Zr (IV) has been developed based on the reaction of 1,4-dichloro-2,5-dihydroxyquinone in a hydrochloric acid medium to form a colored complex which is rendered water soluble by the micellar action of cetylpyridinium chloride (CPC) and measured at λmax 331 nm. Beer's law is obeyed in the concentration range 0-5 µg.ml -1 . The molar absorptivity of the complex, є was found to be 1.6 ×10 4 L.mol -1 cm -1 and Sandell's sensitivity was found to be 5.7 ng.cm -2 . A method for determination of Zr (IV) by second derivative spectrophtometry has also been proposed. The detection limit of Zr (IV) in the derivative method is 6 times lower than that of the zero order method, which shows the higher sensitivity of the derivative method. The method has been applied for determination of Zr (IV) in various samples, and satisfactory results have been obtained.

“…13 Several methods are used to identify indium(III), including atomic absorption spectrometry, 14 voltammetry, 15 spectrophotometry 16 and HPLC. 17 However, only a few liquid or conventional ion selective electrodes (ISEs) have been described for indium(III), [18][19][20] and they exhibit similar drawbacks to such types, such as difficult handling because of the presence of liquids or inner solutions.…”

A novel solid-contact indium(III)-selective sensor based on bis-(1H-benzimidazole-5-methoxy-2-[(4-methoxy-3, 5-dimethyl-1-pyridinyl) 2-methyl]) thiosulfinate, known as an omeprazole dimer (OD) and a neutral ionophore, was constructed, and its performance characteristics were evaluated. The sensor was prepared by applying a membrane cocktail containing the ionophore to a graphite rod pre-coated with polyethylene dioxythiophene (PEDOT) conducting polymer as the ion-to-electron transducer. The membrane contained 3.6% OD, 2.3% oleic acid (OA) and 62% dioctyl phthalate (DOP) as the solvent mediator in PVC and produced a good potentiometric response to indium(III) ions with a Nernstian slope of 19.09 mV/decade. The constructed sensor possessed a linear concentration range from 3 × 10 −7 to 1 × 10 −2 M and a lower detection limit (LDL) of 1 × 10 −7 M indium(III) over a pH range of 4.0-7.0. It also displayed a fast response time and good selectivity for indium(III) over several other ions. The sensor can be used for longer than three months without any considerable divergence in potential. The sensor was utilized for direct and flow injection potentiometric (FIP) determination of indium(III) in alloys. The parameters that control the flow injection method were optimized. Indium(III) was quantitatively recovered, and the results agreed with those obtained using atomic absorption spectrophotometry, as confirmed by the f and t values. The sensor was also utilized as an indicator electrode for the potentiometric titration of fluoride in the presence of chloride, bromide, iodide and thiocyanate ions using indium(III) nitrate as the titrant.
