Determination of Water Quality by Ion Characterization of Van Lake Water

Van Lake is the world’s largest sodium nodule lake, as well as salt water. Van and Bitlis are surrounded by volcanic rocks in the north and west, metamorphic to the south and predominantly sedimentary rocks to the east. Due to this diversity, Van Lake water has attracted attention from researchers in every period in terms of chemical parameters. Lake Van Basin pond water quality studies for the past few years, although the analyses made so far are not made on a regular basis. In this study, concentration levels of anions and cations reflecting the natural quality of Van Lake water were investigated by ion chromatography. As a result of the chemical analysis of the water samples taken from 8 different points and 9 different depths, the average pH value was found at 9.52 and the resulting data is looking at average concentration values of major cations calcium 355.3, magnesium 117.1, sodium 8 612.6, potassium 473.6, lithium 0.3 ppm; from the main anion fluoride 4.8, chloride 8 703.5, bromide 20.5, nitrate 3.7, phosphate 13.6, sulfate 2 900.4 ppm respectively. Under the legislation, the evaluation of the results obtained as a result of the ionic components contained in the water of Lake Van in the Regulation of Surface Water Quality in terms of its parameters according to IV. water quality was found to be in the class. This study includes significant innovations in terms of the techniques used although extensive research. Especially in terms of chromatographic techniques it is likely to make original contributions to the work in this area.
