A square-wave voltammetric method for analysing the colour marker quinizarine in petrol and diesel fuels
(Elsevier B.V., 2007-01-01)
This work presents an electroanalytical method based on square-wave voltammetry (SWV) for the determination of quinizarine (QNZ) in a mixture of Britton-Robinson buffer 0.08 mol L-1 with 30% of acetonitrile. The QNZ was ...

Voltammetric and spectroscopic study of the manganese-quinizarine-quinaldic acid mixed-ligand complex in dimethylsulfoxide
(PERGAMON-ELSEVIER SCIENCE LTD, 1997)
The combination of manganese(II) with quinizarine and the monoanion of quinaldic acid in dimethylsulfoxide yields a soluble deep-blue complex whose Mn-II:Qz(2-):ACQ(-) stoichiometry is 1:1:2. This complex is oxidized in ...
Green Photoluminescent Methodology for Aluminium Traces Quantification in 24-Hour Urine of Subjects with Different Exposition to Tobacco Smoke
(Scientific Research, 2018-10-25)
The aim of this work has been to evaluate the aluminium Al(III) traces contents in 24-hours urine samples from subjects with different tobacco smoke exposition using a new methodology using 1,4-dihydroxy-9,10-anthraquinone ...
Manganese-quinizarin-pyrazinecarboxylic acid mixed-ligand complex in aprotic media. Formation of a manganese(III)-semiquinone binuclear species
(KLUWER ACADEMIC PUBL, 1999)
The monoanion of pyrazincarboxylic acid (PcA(-)), the dianion of quinizarine (Qz(=)) and manganese(II) yield a soluble deep-blue complex in dimethylsulphoxide whose Mn-II:Qz(=):PcA(-) stoichiometry has been established as ...
