Abstract: In combination with microprocessor, by using FIA stopped-flow technique and gradientcalibration, a single standard catalytic kinetic spectrophotometric method is described.Themethod is simply operated and good reproducible.It has been used in determination of trace Mn(Ⅱ) in natural water.The results were in ccordance with those obtained using Otto-Rentsch-Werner method in literature[4,5].

Key words: catalytic kinetic spectrophotometric analysis, FIA, gradient calibration, stopped flow technique, computer control, Mn(Ⅱ)
