The Quality of Yıldız River Water and Determining Trace Elements by Liquid-Liquid Micro-Extraction Analytical Method

The present study was carried out between September 2019 and March 2020 in Yıldız River, which is located within the borders of Yıldızeli district Sivas province used for agricultural irrigation purposes, to determine chemical characteristics river water trace elements. Water’s alkalinity, oxygen demand (COD), chloride (Cl-), calcium (Ca2+), total hardness, phosphate (PO4-P), dissolved reactive (SRP), ammonium nitrogen (NH4-N), nitrate-nitrogen (NO3-N), nitrite-nitrogen (NO2-N), soluble silica (SiO2-Si) concentrations, as well elements (ferrous, lead, cadmium). Moreover, during sampling process, also temperature, oxygen, conductivity, pH, solids measurements were performed. Before using flame atomic absorption spectrometer (FAAS) determining Fe, Pb, Cd samples, a simple, environment-friendly, new ultrasonic liquid-liquid micro-extraction method suggested. Several parameters (pH, ionic fluid amount, dispersive solvent volume, temperature) influencing performance optimized. Under optimized conditions, detection thresholds Fe (II), Pb (II) found be 0.6, 0.15, 1.5 μg L-1, respectively.
