Study on the Colour Reaction of Fe with PF and CTMAB and It'S Application

Zhang Hen

Abstract

In this paper, spectrophotometric determination of ferrum with phenyifluorone and cetyltrimethylammonium bromide is described. The molar absorptivity of the complex is 1. 09×105L. mo1-1.cm-1at 620nm. Beer's Law is obeyed in the range of 0 to 6μg. 25mL-1 of Fe. Satisfactory resultshave been obtained when the coloration is used for determination of ferrum in water and copperminerals.
