Ensuring of the uniformity of measurements for determination of heavy metals traces in solutions with optospectral methods

摘要

The basic techniques for determination of heavy metals impurities for the concentration range from 10{sup}-9 up to 10{sup}-4 % are surveyed. The complex application of optospectral methods-atomic absorption, atomic emission and atomic fluorescence is substantiated. The problem of ensuring of the uniformity of measurements in that field of analysis is raised, and analytical equipment providing the decision of these problems and its application are described.
