A flow injection (FI) manifold based on luminol chemiluminescence (CL) detection for the determination of silicate in freshwaters is described. The molybdosilicic heteropoly acid formed by silicate and ammonium molybdate in acidic conditions generated CL response via the oxidation of luminol. The calibration graph was linear over the range 0.35-140μgSiL -1 (r 2 =0.9974) at 25...
A simple and rapid flow injection (FI) method is reported for the determination of phosphate (as molybdate reactive P) in freshwaters based on luminol chemiluminescence (CL) detection. The molybdophosphoric heteropoly acid formed by phosphate and ammonium molybdate in acidic conditions generated chemiluminescence emission via the oxidation of luminol. The detection limit (3x standard deviation of...
