Abstract

In a method for quantitative determination of iron contained in a test water, a dithionite, such as an unhydrous salt of sodium dithionite is added to the test water first. By this process, the colloidal shaped and sediment shaped iron components contained in the test water are ionized and solved in the water, and the trivalent iron ions contained in the water are reduced to divalent iron ions. Thereafter, a coloring agent which reacts with the divalent iron ions to produce color is added to the test water in which the dithionite has been added, and the quantity of iron in the water is determined by absorptiophotometry. The applicable coloring agents may be, for example, 1,10-phenanthroline and its hydrates, or 2,4,6-tris (2-pyridyl)-1,3,5-triazine.
