Determination of Iodide in Tropical Seaweed (halopterisfilicina)

Seaweed (Halopteris filicina) was analyzed for its iodide content. The iodide content ranges from 0.081 to 0.121 % of the dried weighed sample. Various factors were suspected inhibiting the iodide content. The oxidation method adopted employ the use of 30 % hydrogen peroxide in acidic medium, subsequent extraction with chloroform and titration against 0.05N Sodium Thiosulphate gave an average iodide content of 0.102 % of the dried weighed sample.
