Evaluation method for analytical data of land water using corrected electrical conductivity with ionic strength

Abstract

Considering the significance of possible future problems regarding water quality, it becomes important to obtain accurate and precise data on environmental water samples. For any uses of chemical data in water samples, it is important that measured data satisfy specified levels of reliability. A comparison between calculation and measurement of the electrical conductivity is widely applied to evaluate analytical reliability of wet deposition as well as cation and anion balance. However, because of the high ionic strength, the calculation method of the electrical conductivity for the wet deposition may not be applicable for land water samples, such as river or lake water samples. In this paper, the relation between the measured and calculated electrical conductivity will be discussed. The purpose is to propose a suitable evaluation method of the analytical reliability for land water samples. © 2006 The Japan Society for Analytical Chemistry.
