Abstract
A new approach for the sensitive determination of oxalate was develope d. Iron(II) generated in the photochemical decomposition of iron(III)- oxalate complex was measured by its catalysis of the chemiluminescent luminol reaction in the abscence of added oxidant. A flow-injection co nfiguration is proposed for the determination of oxalate over a concen tration range of 1.0 x 10(-7)-1.0 x 10(-4) M with a throughput of 30 s amples/h. The effect of a large number of potential interferents was i nvestigated and a method devised for the determination of oxalate in u rine.
