Abstract

Van Lake is the world’s largest sodium nodule lake, as well as salt water. Van and Bitlis are surroundedby 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 chemicalparameters. Lake Van Basin pond water quality studies for the past few years, although the analyses made so far arenot made on a regular basis. In this study, concentration levels of anions and cations reflecting the natural quality ofVan Lake water were investigated by ion chromatography. As a result of the chemical analysis of the water samplestaken from 8 different points and 9 different depths, the average pH value was found at 9.52 and the resulting datais 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 aresult of the ionic components contained in the water of Lake Van in the Regulation of Surface Water Quality interms of its parameters according to IV. water quality was found to be in the class. This study includes significantinnovations in terms of the techniques used although extensive research. Especially in terms of chromatographictechniques it is likely to make original contributions to the work in this area.
