Sequential Determination of Nickel and Copper in Waste Waters by Reversed Flow Injection Spectrophotometry

摘要: Abstract A new system using reversed flow injection analysis (rFIA) is described for the sequential determination of nickel and copper in waste waters. The insertion two valves with different functions along FIA manifold allows a simple, fast, versatile photometric pollutants single configuration. results found by proposed method are good agreement as conventional methods, sensitivity greater than that normal technique, sampling frequency 60 h−1. These features made this scheme suitable monitoring polluting species
