Iron(III) has been determined by DCTA titration with p-aminosalicylic acid and sodium azide as indicator at pH 1.4-3.5. The titrations are rapid, simple, accurate and reversible and as little as 0.15 mg of iron(III) can be determined in the presence of up to 100 times as much of certain ions. Cadmium, zinc, lead, copper(II), aluminium, thorium, oxalate, phosphate, fluoride and sulphide interfere. The method is utilized for determination of iron(III) in presence of copper(II) or lead and in limestone, cement and haemetite.
