Assay Methods - Iodimetric and Iodometric Titrations

ASSAY METHODS

Assay methods involving iodine can be categorized under the following heads namely :

A. Iodimetric Assays :

(a) Direct titration with iodine,

(b) Residual titration method : i.e., excess of iodine is titrated with sodium thiosuphate,

B. Iodometric Assays : 

i.e., release of iodine and subsequent titration with sodium thiosulphate.
