Kompleksometrititraus

Kompleksometrititraus is a method used to determine the concentration of a specific metal ion in a solution. This technique is based on the formation of a colored complex between the metal ion and a suitable ligand, which can then be measured spectrophotometrically. The ligand used in this method is typically a chelating agent that forms a stable complex with the metal ion, resulting in a characteristic absorption spectrum.

The principle behind kompleksometrititraus involves the addition of a known excess of the ligand to the solution containing the metal ion. The complex formed between the metal ion and the ligand absorbs light at a specific wavelength, which can be measured using a spectrophotometer. The concentration of the metal ion can be determined by comparing the absorbance of the solution to a calibration curve prepared using standard solutions of known metal ion concentrations.

The choice of ligand and the wavelength of light used for measurement depend on the specific metal ion being analyzed. Common ligands used in kompleksometrititraus include EDTA (ethylenediaminetetraacetic acid) and its derivatives, which can form stable complexes with a wide range of metal ions. The method is widely used in analytical chemistry for the determination of metal ion concentrations in various samples, including environmental, biological, and industrial materials.
