A simple method has been developed for the individual and simultaneous determination of titanium(IV) and molybdenum(VI) using salicylaldehyde p-hydroxybenzoylhydrazone (SAPHBH) in presence of Triton X-100.
Without any prior separation.Beers law is obeyed between 0.15-2.0 and 0.20-2.51 mugmL~(-1) concentration of Ti(IV) and Mo(VI) at 470 and 410 nm,respectively.
The molar absorptivity and Sandells sensitivity of the coloured species at pH 2.6 are 2.0 x 10~4 and 3.5 x 10~4 Lmol~(-1)cm~(-1) and 2.5 and 2.7 ng cm~(-2) for Ti(IV) and Mo(VI),respectively.
