A spectrophotometric flow-injection method based on a diazo-coupling reaction is proposed for the simultaneous determination of nitrite and nitrate. Nitrate is reduced to nitrite by using a reductor column which is formed by filling part of the sample loop with copperized cadmium. The flow system pr

A method was developed for the determination of V(V) in the presence of V(N) using flow-injection analysis (FIA). In this method, V(V) forms a coloured complex with 4-(2-pyridylazo)resorcinol (PAR), while a complexing agent, 1,2cyclohexanediaminetetraacetic acid (CDTA) was added to mask the interfer
A spectrophotometric, continuous flow-injection, merging zones manifold including an enzyme reactor was used for the determination of magnesium ion in serum by exploiting the activating effect of MgfII) on the hydrolysis of o-nitrophenyl-B-o-galactopyranoside by j?-o-galactosidase immobiliied on con
## Abstract A simple and rapid flowβinjection chemiluminescence method has been developed for the determination of dithiocarbamate fungicide thiram based on the chemiluminescence reaction of thiram with ceric sulfate and quinine in aqueous sulfuric acid. The present method allowed the determination
