Abstract
A flow injection analysis system is described for the simultaneous determination of several ions in a single sample using a combination of potentiometric and spectrophotometric detection. A composite manifold has been designed consisting of a flow cell containing four ion-selective electrodes and two spectrophotometric transducer flow cells. The system has been applied to the determination of K+, Ca2+, NH4 +, Cl–, NO3 – and PO4 3– ions in a number of plant nutrient solutions.Keywords
