Determination of iodine content in different brands table salt of Bangladesh

Abstract

IDD (Iodine deficiency disorders) are recognized as a major global public health problem; it is possible to root out this problem by universal salt iodization. The study was designed to determine iodine concentration in different branded salt collected from different area of Bangladesh. All samples were collected both Dhaka and out of Dhaka city. Concentration of iodine in salt was determined by iodometric titration method. Reagent was K2Cr2O7, standardized Na2S2O3, KI, NaHCO3, starch, concentrated HCl, H2SO4. Most of the salts collected show iodine level to be in the acceptable range. Result showing that out of seven brand only one shown to has a poor content of iodine. It can be decided from the result that most of the people of our country are now using iodized salt. Evidence is now available from both controlled trials and successful iodization programs that these disorders can be successfully prevented by correction of iodine deficiency. A major achievement is the spectacular reduction of IDD in our country that has implemented universal salt iodization.
