摘要
FIELD: chemistry.;SUBSTANCE: invention relates to method and apparatus for determining number of different substances in liquid sample. Since device is extremely stable, it can be repeatedly used with such samples of very hard water, as water from petroleum refinery settler. Device uses at least one optical analysis method, not depending on volume and/or concentration, in order to determine one of following properties: hydrogen ion exponent pH, amount of chloride and/or amount of iron in sample. Optical property may be colorimetric, fluorescent, or both, wherein it can be result of adding into sample dyes, complexing agents, compounds, causing turbidity, and other reagents, causing optical effects. Since measurements do not depend on concentration and volume, they can be carried out continuously and quickly.;EFFECT: method involves use of BDD electrode for oxidation of substances (such as sulfoxide compounds), which otherwise would hinder for optical analysis.;13 cl, 11 dwg
