ABSTRACT
Sodium is an essential element to regulate the various functions of body. There are different sources of sodium such as table salt, breads and rolls, sandwiches, soups, cold cuts and cured meats, savory snacks, chicken etc. However, the excessive intake of sodium may cause health issues such as hypertension, brain strokes, renal irregularity, heart attack etc. Various analytical techniques including atomic absorption spectroscopy, chromatography methods, ion selective electrode method, laser-induced breakdown spectroscopy, complexometric titration method and thermometric endpoint titrimetry are developed to determine the quantity of sodium. Spectrophotometric methods are cheap, easy to handle and more precise to quantify sodium in food contents.
