Catalytic reactions have been utilized as indicator reactions for
kinetic-catalytic methods of trace analysis[8,9]. Since the measurement includes time as an experimental variable, care is needed to ensure that mixing of reagents takes place at regular time
intervals to obtain highly accurate results. Such precise control of
the reaction conditions can be easily accomplished by employing

flow injection analysis (FIA) techniques[10]. Highly sensitive flow
injection (FI) catalytic spectrophotometric methods are a very
useful and versatile technique for trace metal determinations in
natural and/or drinking water samples[11]. Many reports on FI
catalytic spectrophotometric methods for the determination of
vanadium[12–14]and iron[15–17]have been published so far.
