“…These should be considered and treated carefully to prevent potentially severe interfering effects while carrying out atomic emission measurements. 16 Karadjov et al 30 studied spectral interferences in the determination of Re in Mo and Cu concentrates by ICP-OES, and observed that Re emission lines at 197.248, 221.426 and 227.528 nm were affected by OH bands, as well as by Al, Cu, Fe, Mo and Ti emission lines. Daskalova and Boevski 31 reported interfering lines for nearly 56 investigated spectral lines monitored in the determination of trace elements in environmental materials by ICP-OES.…”

“…18,19 The World Health Organization (WHO) suggests that the CN − concentration in drinking water should be less than 0.07 mg/L. 11 For the analysis of these cations and anions in aqueous samples, several techniques such as ion chromatography, 20 high-performance liquid chromatography−mass spectrometry (HPLC-MS), 21 gas chromatography−mass spectrometry (GC-MS), 22 inductively coupled plasma-optical emission spectrometry (ICP-OES), 23 atomic absorption spectroscopy (AAS), 24,25 and inductively coupled plasma−mass spectrometry (ICP-MS) 26 can be used as either direct or indirect methods. These techniques usually provide high accuracy, precision, and sensitivity, but they require tedious sample preparation and high instrument maintenance costs.…”

A novel spirobifluorene derivative bearing two bissulfonamido groups is successfully synthesized by Sonogashira coupling. This compound exhibits a strong fluorescence quenching by Cu(II) ion in a 50% mixture between acetonitrile and 20 mM pH 7.0 N -(2-hydroxyethyl)piperazine- N ′-ethanesulfonic acid (HEPES) buffer with a detection limit of 98.2 nM. However, this sensor also shows ratiometric signal shifts from blue to yellow in the presence of Zn(II), Pb(II), and Hg(II) ions. The static quenching mechanism is verified by the signal reversibility using ethylenediaminetetraacetic acid (EDTA) and the Stern–Volmer plots at varying temperatures. The Cu(II)–spirobifluorene complex shows a highly selective fluorescence enhancement upon the addition of CN – ion with the detection limit of 390 nM. The application of this complex for quantitative analysis of spiked CN – ion in real water samples resulted in good recoveries.

“…Copper is likewise a fundamental component for hemoglobin amalgamation, rectify nerve working, and bone improvement, Copper insufficiency causes ischemic coronary illness, iron deficiency, and abnormal wool growth (3). Many techniques are used to determine copper including atomic absorption spectrometry (4)(5)(6), potentiometry (7)(8)(9)(10)(11), inductive coupled plasma-emission spectrometry (12), inductive coupled plasma-mass spectrometry (13), and flow injection catalytic photometric method (14).…”

Spectrophotometric method was developed for the determination of copper(II) ion. Synthesized (2,2[O-Tolidine-4,4-bis azo]bis[4,5-diphenyl imidazole]) (MBBAI) was used as chromogenic reagent at pH=5. Various factors affecting complex formation, such as, pH effect, reagent concentration, time effect and temperature effect, have been considered and studied. Under optimum conditions concentration ranged from (5.00-80.00) µg/mL of copper(II) obeyed Beer`s Low. Maximum absorption of the complex was 409nm with molar absorpitivity 0.127x10 4 L mol -1 cm -1 . Limit of detection(LOD) and Limit of quantification were 1.924 and 6.42 μg/mL, respectively. The stoichiometric composition of the chelate is 1:2 (Cu:MBBAI). Experimental results for studying some selected ions as interference were reported. The developed method was successfully applied to determine copper (II) ion in dental filling.
