A sensitive spectrophotometric method for the determination of titanium (IV) using gallacetophenone phenylhydrazone with applicatin to ilmenite

The most common spectrophotometric reagents employed for the determination of titanium (IV) are hydrogen peroxide[1] and tiron[2]. However, N-benzoylN-phenylhydroxylamine[3,4] and N-phenyllaurohydroxamic acid[5] are introduced for extractive spectrophotometric determination of titanium (IV). Aroylhydraones such as pyridoxal salicyloylhydrazone[6], diphenylglyoxal bis (benzoylhydrazone)[7] and dipyridylglyoxal bis (benzolyhydrazone)[7], salicylaldehyde 2-methyl isonicotinoylhydrazone[8], 1,2cyclohexanedione bis (benzoylhydrazone)[9] are also extensively employed for the spectrophotometric determination of titanium. Sane et al[10] have developed a spectrophotometric method using 5,6-dibromogallacetophenone as a reagent. The hydrazones emD.Venkataramana Reddy*1, A.Varada Reddy2 S.G.Govt.
