“…Further increases in KMnO 4 concentration resulted in a slow decrease in the emission intensity. The decrease in emission beyond 6.0 × 10 −5 mol/L KMnO 4 was probably due to KMnO 4 absorbing the emitted light . Therefore, a concentration of 6.0 × 10 −5 mol/L KMnO 4 was chosen for subsequent work.…”

Ultra-weak chemiluminescence (CL) from the reaction of iodide and KMnO was strongly enhanced by carbon nanodots (CNDs) in an acidic medium. The CL intensity was directly proportional to the concentration of iodide in the solution. Therefore, a flow-injection CL system with high sensitivity, selectivity and reproducibility is proposed for the determination of iodide. The proposed method exhibited advantages over a linear range of 3.0 × 10 -1.0 × 10 mol/L and had a detection limit of 3.5 × 10 mol/L. The method was successfully applied to the evaluation of iodide in food samples with recoveries of between 96 and 103%. The relative standard deviations were 2.1 and 4.1% for intra- and inter-assay precision, respectively.

“…Thus, 0.1 mmol L -1 was selected for application of the proposed method to the chemiluminometric determination of antu. The CL signal decreased above 0.2 mmol L -1 , likely as the result of permanganate absorbing the emitted light ( − ).…”

A novel chemiluminescence method for the determination of antu has been developed based on the reaction between potassium permanganate in acid medium with this rat-poison in the presence of formaldehyde as an emission enhancer. The main feature of the system used is that the recording of the whole chemiluminescence intensity-vs-time profiles can be obtained, using the stopped-flow technique in a continuous-flow system. This enables the use of three quantitative parameters adjustable via software settings, one of them a typically kinetic parameter, such as rate of the light-decay reaction, and the others conventional parameters, such as maximum emission intensity and total emission area, which are proportional to the analyte concentration. The optimum chemical conditions for the chemiluminescence emission were investigated. The effect of common emission enhancers, such as formic acid, formaldehyde, glutaraldehyde, acetaldehyde, quinine, fluorescein, rhodamine B, and rhodamine 6G, was studied. The parameters selected were sulfuric acid 4.0 mol L(-)(1), permanganate 0.1 mmol L(-)(1), and formaldehyde 1.0 mol L(-)(1). The calibration graphs obtained with each one of the measurement parameters were linear for the concentration range from 0.05 to 3.00 microg mL(-)(1). The detection limits ranged from 0.005 to 0.010 microg mL(-)(1), and RSD values (n = 10) of 0.99-1.79% at a 0.30 microg mL(-)(1) concentration level and 1.71-2.22% at a 1.0 microg mL(-)(1) concentration level were obtained. The present chemiluminescence procedures were applied to the determination of antu in different kinds of samples, such as river water, wheat, barley, and oat grain samples. Recovery values not significantly different from the spiked amount were found for these determinations.

“…Tsaplev suggested that molecular nitrogen was formed in an electronically excited state, and that energy is transferred from this reactive intermediate to the emitting species. We have recently shown that the chemiluminescence spectrum for the oxidation Chemiluminescence has been detected during the oxidation of hydrazine and its derivatives with acidic potassium permanganate (148,149) and again molecular nitrogen was postulated to be the emitting species (149). However, spectroscopic and chemical evidence showed that the chemiluminescence elicited from various reactions with acidic potassium permanganate originated from a triplet state of manganese(II) and was independent of analyte structure (150).…”

Hypohalites and related oxidants as chemiluminescence reagents: a review

et al. 2004

View full text Add to dashboard Cite

This review concerns the use of hypochlorite, hypobromite and related oxidants (such as N-bromosuccinimide and 1,3-dibromo-5,5-dimethylhydantoin) as chemiluminescence reagents and includes references to 249 papers that were published prior to mid-2003. Particular emphasis has been placed on proposed emitting species and the mechanisms of the light-producing pathways. The analytical applications of this chemistry have been summarized in three tables: (1) quantification of hypohalites and related compounds (including halides, which are initially oxidized); (2) enhancement or inhibition of luminol chemiluminescence; and (3) direct chemiluminescence reactions with hypohalite reagents.
