Effect of model ligands on iron redox speciation in natural waters using flow injection with luminol chemiluminescence detection.
Fe(II) determinations for both luminol FI-CL methods were affected by submicromolar concentrations of redox-active compounds, strong iron binding ligands, and compounds with electron-donating functional groups in both high-purity water and seawater. Expand
Determination of nanomolar concentrations of phosphate in freshwaters using flow injection with luminol chemiluminescence detection
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. TheExpand
Determination of nitrate and nitrite in freshwaters using flow-injection with luminol chemiluminescence detection.
A simple and sensitive flow-injection method for the determination of nitrate and nitrite in natural waters, based on luminol chemiluminescence (CL) detection, is reported and the results obtained were in good agreement with those obtained by an automated segmented flow analyser reference method.

Investigation of iron(III) reduction and trace metal interferences in the determination of dissolved iron in seawater using flow injection with luminol chemiluminescence detection.
A detailed investigation into the performance of two flow injection-chemiluminescence (FI-CL) manifolds for the determination of sub-nanomolar dissolved iron (Fe(II)+Fe(III)), following the reduction of Fe(III) by sulphite, in seawater is described. Expand
Chemiluminescent determination of cholesterol by flow injection analysis with immobilized cholesterol oxidase
Abstract A rapid and sensitive chemiluminescent assay for the determination of cholesterol in blood serum is described. The procedure is based on the measurement of chemiluminescence emissionExpand
