“…Other, more pristine natural water sites have water suitable for Fe 2+ quantitation using the FeLume, as our site in the Snowy Range showed, but its effectiveness should be determined on a site-by-site basis. All samples containing Fe(III)-organic complexes (especially oxalate) should be kept dark prior and during analysis to ensure photoreduction of these complexes does not result in altering [Fe 2+ ] determination [ 35 , 61 - 65 ].…”

An evaluation of flow-injection analysis with chemiluminescence detection (FIA-CL) to quantify Fe2+(aq) in freshwaters was performed. Iron-coordinating and/or iron-reducing compounds, dissolved organic matter (DOM), and samples from two natural water systems were used to amend standard solutions of Fe2+(aq). Slopes of the response curves from ferrous iron standards (1 – 100 nM) were compared to the response curves of iron standards containing the amendments. Results suggest that FIA-CL is not suitable for systems containing ascorbate, hydroxylamine, cysteine or DOM. Little or no change in sensitivity occurred in solutions of oxalate and glycine or in natural waters with little organic matter.

Main observation and conclusion A new chemiluminescence (CL) reagent named 4‐amino‐5‐thiocyanato‐phthalyl‐hydrazine (iso‐luminol‐SCN) is synthesized by the bromide‐mediated substitution reaction of iso‐luminol with sodium thiocyanate in dimethyl formamide (DMF) at room temperature. Strong CL is observed for iso‐luminol‐SCN oxidized by hydrogen peroxide (H2O2) in the presence of Fe2+, with the CL intensity strongly depending on the concentration of Fe2+ and being hardly interferred by other common metal ions. Based on this fact, a flow injection CL method is established for the high sensitive and selective determination of Fe2+. The CL intensity was linearly correlated with the concentration of Fe2+ in the range of 1.0 × 10–8 mol·L–1 to 1.0 × 10–5 mol·L–1 following the equation CLnet = 166.3c + 57.7 (c, ×10–6 mol·L–1; n = 7; R2 = 0.9988). The detection limit is calculated to be 3.2 × 10–9 mol·L–1 Fe2+ based on the 3S0/K principle. The relative standard deviation (RSD) was 3.7% for 1.0 × 10–6 mol·L–1 Fe2+ (n = 11), a support for the precision of Fe2+ measurement. The recoveries of Fe2+ were obtained in the range of 98.8%—101.6% in three real water samples, showing the applicability and reliability by the proposed method. The possible CL mechanism is proposed based on the kinetic characteristic of the CL reaction and the CL spectrum.
