This paper describes the determination of Pb and Cu with a Nafion-modified glassy carbon electrode MnCo2O4 nanoparticles as working for anodic stripping voltammetry. were accumulated in HCl/KCl (0.1 mol dm−3) at potential –1.4 V (vs. Ag/AgCl electrode) 480 s, followed by linear sweep voltammetry (ASV) scan from –1.0 to +0.5 V. Under optimum conditions, calibration curves range 0.01 – 8 5 mg dm−3 Cu, respectively. Effect sample dilution, accumulation time optimized. A study interfering...
Proteomic approach in combination with mass spectrometry demonstrates a great potential for identification of proteinaceous materials works art. In this study we used linear trap quadrupole Orbitrap (LTQ-Orbitrap), state-of-the-art spectrometer parts per million accuracy analyses peptides behind tryptic hydrolysis. After the efficiency proteomic method was confirmed reference and model samples, micro-samples from historical paintings were first time analysed using technique. Superior...
A gas-diffusion flow injection method with amperometric detection for indirect copper determination on a silver electrode is developed. The through system equipped two valves and unit. In the first step, signal of cyanide solution was recorded. following step in presence measured. Interferences (Cd(II), Co(II), Ag(I), Ni(II), Fe(III), Hg(II) Zn(II)) were investigated successfully removed. calibration graph linear range 1-90 ?mol dm-3 copper, correlation coefficient 0.993, regression equation...
