Analysis of the error in the results of impurities concentration measurement in solutions

Abstract

The paper studies the influence of impurity concentration and measurement conditions on the error of measurement results. The relevance of this work is due to the need to improve reliability of measurement results in conditions of deterioration of the environmental performance of water bodies and to identify cases of multiple excesses of maximum permissible standards by concentration of pollutants. The method of measurements is considered and the sources of possible errors are determined. A significant influence on the error of the result of determining the concentration of pollutants of both the type of pollutant and the process of sample preparation for research is shown.
