Spectrophotometric Determination of Copper
The utility of Patton and Reeder’s indicator, HHSNNA, for the trace spectrophotometric and visual colorimetric determination of Cu 2+ is explored. A wine red complex of composition 1:1 is found to be formed between Cu 2+ and HHSNNA. The complex has λmax at 530 nm with ε = 25,558 L mole -1 cm -1 and is stable for more than 2 hrs. Beer’s law is obeyed between 0 to 1.5 ppm. The developed procedure...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

15 صفحه اولSpectrophotometric determination of trace amount of copper(II) ion based on complexation with an anthraquinone derivative.
The spectrophotometric determination of Cu(II) with an anthraquinone derivative (Alizarin Red S) has been investigated. The experimental conditions, such as the pH of the sample and concentration of ligand, were optimized. This method is simple and sensitive for determination of Cu(II) ion. The interfering effects of diverse ions were investigated. Copper ion was determined by measuring the abs...
