Method for determining the concentration of metal ions and the metal indicator for determining the concentration of metal ions

摘要

determination of the concentration of the metal ions is that shall be drawn up at least two reference solutions of a different metal ion content, the following set and the same for each standard solution is measured quantity metalowskau017anika, uv vis spectrum absorbcyjne each standard solutions and sets a calibration curve of absorbance from the content of metal ion dependence.then the test solution, the same rate and in the same quantity as the standard solution, uv vis absorption spectrum is measured, from which read absorbance values, with the same wavelength as in standard solution and calibration curve read content ion m etalu in test solution, characterised by the fact that as the applied salt 5 - (8 - hydroksychinolino) - 77 - dimethyl - 7h - indolo [1,2] - and chinoliniowu0105 of model 1, where x - is anion of acid solotwu00f3rczego.
