The characteristic red chemiluminescence from reactions with acidic potassium permanganate: further spectroscopic evidence for a manganese(ii) emitter

Abstract

A direct comparison of the laser-induced photoluminescence of manganese(ii) with the chemiluminescence from the reaction between acidic potassium permanganate and sodium borohydride was used to confirm that the characteristic red emission from this widely used chemiluminescence reagent emanates from an electronically excited manganese(ii) species.

Selectivity and potential interference from phenolic compounds in chemiluminescence methods for the determination of synephrine

“…These values are in agreement with those reported for many other analytes with these two reagent systems (18,21). In both cases, the luminescence emanates from an excited manganese(II) species (22,48); the presence of polyphosphates in the permanganate reagent causes a shift to shorter wavelengths (22).…”

Flow-Injection Determination of Retinol and Tocopherol in Pharmaceuticals with Acidic Potassium Permanganate Chemiluminescence

“…In a number of articles [30][31][32] dealing with the oxidation of various compounds with acidic potassium permanganate it is proposed that the CL emitter in these reactions is the excited Mn(II) species. In a recent communication, Adcock et al 33 show a comparison of the laser-induced photoluminescence of Mn(II) with chemiluminescence from the reaction of acidic potassium permanganate and sodium borohydride to confirm that the characteristic red emission from acidic potassium permanganate emanates from an electronically excited Mn(II) species. In an earlier investigation, Barnett et al 34 negated the possibility of generating CL from potassium permanganate oxidations via singlet oxygen, sulfur dioxide, molecular nitrogen or nitric oxide species.…”

A rapid antioxidant assay based on acidic potassium permanganate chemiluminescence

“…The reaction of acidic potassium permanganate with various organic molecules results in an emission of light from an electronically excited manganese(II) species (Adcock, Francis, & Barnett, 2009;Adcock, Francis, Smith, & Barnett, 2008). Although many compounds react with this reagent, the intensity of the short-lived 0308-8146/$ -see front matter Ó 2010 Elsevier Ltd. All rights reserved.…”
