SPECTROPHOTOMETRIC METHOD FOR THE DETERMINATION OF IRON SPECIES IN THE PRESENCE OF FERRIC IRON
Journal Title: Topics in Civil, Environmental & Building Engineering (TICEBE) - Year 2017, Vol 1, Issue 2
Abstract
The high concentration of ferric(Fe3+) in sample has interference on the determination of ferrous(Fe2+) concentration by spectrophotometric method which 1, 10-phenanthroline is used to as chromogenic agent. Appropriate concentration of fluorine ion (F-) can complex Fe3+ to eliminate interferences which the F- concentration is 13.3 time greater than that of Fe3+. The temperature and light do not affect the masking action of F-. Low temperature and dark conditions favour the stability of chromophoric complex. This method is suitable for determination iron species in the presence of high concentration of Fe3+ in sample.
