Determination of Copper and Zinc in Sugar-
نویسنده
چکیده
Since the introduction by Walsh12 in 1955 of atomic absorption spectrophtometry as an analytical method, it has found application in many fields as a means of rapid analysis of certain metallic elements at very low concentrations. The analysis of agricultural materials, i.e., leaves, soil extracts and fertilizers is one sphere in which atomic absorption has been applied by several workers1, 2, 4, for the analysis of Na, Mg, Ca, I< as well as Cu and Zn. This method has a number of advantages over the usual colorimetric and flame photometric determinations of these elements; (a) it is relatively free from interference by other elements in the sample, (b) it has a higher sensitivity than the flame photometric methods and (c) it is much faster than the usual colorimetric methods.

Zinc is one of the essential elements in biological system. The role of this element in many enzymes has been proved. Zinc has an antagonistic effect on the toxic elements such as cadmium, as both binds to a carrier protein called metalothionein . Zinc can be found in atmosphere of different industrial environment. Due to its importance, it's concentration in the serum of 399 Male workers of sa...

In this work, we developed a method based on ultrasound-assisted emulsification microextraction (USAEME) for the determination of zinc and copper by flame atomic absorption spectrometry (FAAS). The method is based on the use of the organic solvent carbon tetrachloride (CCl4) as an extraction solvent. In order to obtain a high enrichment factor, the effect of different parameters affecting the c...
