EXTRACTION AND DETERMINATION OF Cd, Co, Se, V AND Ag LEVELS IN COW?S MUSCLE, LIVER, KIDNEY, LUNG, SPLEEN AND BRAIN SAMPLES

A deep eutectic solvent (DES) consisting of oxalic acid and choline chloride was prepared and used to extract Cd, Co, Se, V, and Ag from meats. The metal levels were determined in muscle, liver, kidney, lung, spleen, and brain samples using ICP-OES. The total youden blank method was employed to eliminate the matrix effect. The order of Cd concentration in the cow's organs was spleen> brain>lung>liver>kidney>muscle. The higher and lowest concentration of Co was determined in the lung and muscle samples. Se was found in all kinds of examined cow's parts and the higher concentration was determined in the liver samples. V was not determined in the muscle and spleen samples and the abundance order in the cow's part was lung>liver>brain>kidney. Ag was determined in only one of the kidney samples.
