Determination of trace amount of titanium in 2. 5% Nb-Zr alloy by anion exchange separation and sulfo salicylic acid photometry

Technical Report:

Abstract

A trace amount of Ti in 2.5% Nb-Zr alloy can be determined by a combined method of the characteristic anion exchange separation of Ti from Nb and the absorption photometry of Ti with sulfo salicylic acid. The alloy (1g) was dissolved in 5 ml of HF (1 + 1), and 5 ml of HNO/sub 3/ was added to them. The resultant 5M HF - 6M HNO/sub 3/ mixed acid solution was passed into an anion exchange resin column with 10 mm internal diameter and 100 mm high, at the rate of 1 to 2 ml/min. Niobium was adsorbed on to the column, through which Ti passed. The collected passing and washing solutions were converted into H/sub 2/SO/sub 4/ medium by twice successive fuming treatments. The solution was transferred into a volumetric flask of 50 ml, and 10 ml of 10% sulfo salicylic acid in H/sub 2/SO/sub 4/ was added. Diluting to a mark with H/sub 2/SO/sub 4/, the solution was allowed to stand for 15 min. Titanium was then determined by measuring absorption intensity at the wavelength of 410 mm. The influence of coexisting elements on the coloration of Ti and some adsorption conditions of Nb was experimentally investigated by  More>>

The influence of coexisting elements on the coloration of Ti and some adsorption conditions of Nb was experimentally investigated by using /sup 95/Nb as a tracer. The experiment revealed that the removal of Nb is essential, and that higher HF concentration and lower HNO/sub 3/ concentration contribute to higher Nb adsorption. A variable rate type cockless column is useful for this routine analysis. The standard deviation and the coefficient of variation of analysis are 1.3 and 4.06% respectively for the concentration level of 32 ppm Ti (NZ-3).}
