| Abstract: | new method of flow injection analysis withmanifold convergence utitlizing model 72l spectropho-tometer for thedetermination of micro amount of tita-nium using o-nitrophenylfluorone andcetyltrimethylammonium bromide has been developed.The optimal reaction conditions and instru-mental parameters have been selected in detail.Themethod is simple, rapid,sensitive and selective. It hasbeen usedtodetermine micro amount of titanium inalloy steels and pure aluminium samples with repro-ducible results. |
