“…3 There are several analytical techniques for determination of Mn 2+ . Flame and electrothermal atomic absorption spectrometry (FAAS, ETAAS), 4,5 inductively coupled plasma techniques (ICP-OES, ICP-MS), 6 neutron activation analysis, 7 X-ray fluorescence, 8 voltammetry, 9 and molecular absorption spectrophotometry 10 are typical determination methods. Despite their satisfactory limits of detection (LOD), ICP and AAS are costly and destructive methods.…”

Eosin-Y exhibits high affinity and emission based spectral response to most of the major ions in water samples. In the present study we performed selective spectrofluorimetric analysis of manganese with eosin-Y in the presence of potential interferents. We employed green chemistry reagents, ionic liquids (ILs) and two different micelles, to suppress the effect of conventional cations and anions on the response of eosin-Y. The experimental data revealed that different test moieties caused enhanced analytical response to Mn 2+ . The highest analytical signal of eosin-Y was obtained in the presence of Triton X-100 at a concentration of 2.0 × 10 −3 mol L −1 . Presence of the green chemistry reagents ILs enhanced the limit of quantification for Mn 2+ 10-fold with respect to the IL-free moieties. The interfering effects of the metal ions of Ca 2+ , Cu 2+ , Hg + , Hg 2+ , As 5+ , Li + , Al 3+ , Cr 3+ , Co 2+ , Ni 2+ , and the anionic groups were completely suppressed in the presence of the ILs and micelles. Additionally, the tolerance limit of Na + and Zn 2+ ions increased 6-fold in the presence of IL and sodium dodecyl sulfate. The presented method did not use any harmful conventional solvents and was employed successfully for the detection of Mn 2+ ions in real water samples.

Development of a Sensor Based on Poly(1,2‐diaminoanthraquinone) for Individual and Simultaneous Determination of Mercury (II) and Bismuth (III)

Contamination of natural water by mercury (Hg 2 + ) and bismuth (Bi 3 + ) metal ions have been extensively studied due to their toxic effects. A validated square-wave anodic stripping voltammetry (SW-ASV) method for determining Bi 3 + and Hg 2 + ions individually and simultaneously is described. A new electrochemical sensor was constructed using a gold (Au) electrode that has been modified with poly(1,2-diaminoanthraquinone) (p-1,2-DAAQ). Scanning electron microscopy, cyclic voltammetry, and electrochemical impedance spectroscopy were used to characterize the p-1,2-DAAQ/Au modified electrode. Factors such as the polymer film thickness, electrolyte, square wave parameters and preconcentration conditions were optimized to improve the performance of the modified Au electrode. Good linear responses were achieved in the concentration ranges of 1-200 μg L À 1 and 1-50 μg L À 1 forBi 3 + and Hg 2 + , respectively, and the limits of detection were 0.27 μg L À 1 (Bi 3 + ) and 0.29 μg L À 1 (Hg 2 + ). The interference study results illustrated the high selectivity of the modified electrode for detection of Bi 3 + and Hg 2 + . The proposed SW-ASV method was successfully applied for Bi 3 + and Hg 2 + analyses in different real water samples.
