Abstract:
A spectrophotometric method has been developed for the direct determination of total iron in titania slag leach liquor containing Fe(II), Fe(III), Ti(IV), Ca(II), Mg(II) etc., using thiocyanate as a complexing agent. The iron complex absorbs at the wavelength 474-479nm. Beer-Lambert's Law obeys within the range of 0.1-0.9mg/ml of iron. Iron determination by the present method, compared with the titrimetric method, shows good agreement.
