| Abstract: | A sensitive test for nanogram quantities of titanium(IV) is proposed. A resin spot test technique is applied to the colour reaction of titanium(IV) with tiron. The limit of identification is 26 ng of titanium(IV) (1:1.5·106) after 50 min standing. Vanadium(V), chromium(VI), molybdenum(VI) and uranium(VI) interfered seriously. Iron(III) could be masked with EDTA, and iron(III) and titanium (IV) were detected simultaneously. |
