Selective Complexmetric Determination of Titanum (IV) by Using 5-Sulphosalicylic Acid as Releasing Agent %K Titanium determination %K Complexometry %K 5-Sulphosalicylic acid %K Releasing agent %R %X A complexometric method for the determination of titanium in the presence of other metal ions based on the selective masking ability of 5-sulphosalicylic acid towards titanium is described. Titanium (IV) present in a given sample solution is complexed with a known excess of EDTA and surplus EDTA is titrated against zinc sulphate solution at pH 5-6 using xylenol orange as the indicator. A known excess of 10% solution of 5-sulphosalicylic acid is then added. The mixture is then shaken well and the EDTA released from Ti-EDTA complex is titrated against the standard zinc sulphate solution. Reproducible and accurate results are obtained for 0.96 – 28.75 mg of titanium (IV) with relative error ± 0.17% and standard deviations ≤ 0.02 mg. The interference of various ions is studied. This method was applied to the determination of titanium (IV) in its alloys. %U https://ijac.journals.pnu.ac.ir/article_938_4b883d3008c9bd707a42fb4cb6744d3d.pdf
