Abstract

Salt, which is the main nutrient, is a very important raw material in the life of living organisms and industry. Salt production and consumption have improved and increased due to technological developments and industrialization. Salt has been used in the world and in our country since very ancient times. It is used in many fields, especially in the chemical industry, metallurgy, textile, medicine, and agriculture. In addition to sea, lake and spring salts, Turkey has very rich rock salt reserves. The Neogene aged Çankırı-Çorum Basin is one of the important basins where evaporitic formations are observed in the Central Anatolia region. Chemical analyses were carried out to determine the amount of heavy metal in salt samples taken from Oligocene aged units observed in the area between Ocabaşı and Eskikışla springs (Delice) in the Çankırı-Çorum basin. SEM-EDX, XRF and ICP-OES devices were used to determine the geochemical properties and quantities of heavy elements. According to the results of XRF, Na % ( 33.70-38.30), Cl %(52.10 - 57.70) SO3 %(0.75-1.93), Al2O3 %(0.90-1.93), CaO %(0.58-2.69), MgO %(0.40-1.41) Fe2O3 % (0.18-0.64), SiO2 %(1.75-4.95), SrO, % (<0.010), BaO % (<0.010), Cr2O3 %(<0.010), K2O %(0.008-0.25), MnO %(<0.010) results are found. In the determination of heavy metals made with ICP-OES, it was determined that the heavy metals (Hg, As, Pb, Cd) published in the Turkish food codex salt communiqué were below the limit values.
