Hydrogeochemistry: natural waters in full view

Abstract

A new method has been proposed for identifying the type of natural waters, based on the measurement of the refractive index and the density. Previously, using the data on the refractive indices and densities of the solutions of salts the macro components of natural waters (chlorides and sulfates of sodium, calcium, magnesium, and sodium bicarbonate), we constructed an identification card (coordinates: refractive intercept specific Eijkman refraction) on the basis of which it is an easy manner to establish if the test sample of water belongs to a particular type of anion (chloride, sulfate, bicarbonate, mingled), and cation subtype (sodium, calcium, magnesium, combined). The application of a new method of identification of natural waters is demonstrated on the example of the analysis of the samples of oil fields stratal waters, seawater and drinking medicinal-table mineral water
