"Sequential Flow Injection Voltammetric Determination Of Phosphate And Nitrite By Injection Of Reagents Into A Sample Stream"
Analyst 1984 Volume 109, Issue 1 Pages 19-21
Arnold G. Fogg and Nuri K. Bsebsu

Abstract: A modification of flow injection analysis is described, in which the sample (e.g., hydroponic fluid) is used as the eluent and reagents for determination of the individual components are injected sequentially into the sample stream. The method is illustrated by determination of PO43- and NO2- in a sample with use of acidic molybdate solution and acidic KBr solution as reagents, respectively, and voltammetric detection at a vitreous-carbon electrode. Down to 5 µM-PO43- and 50 µM-NO2- could be determined by this method; the response to PO43- was rectilinear.
