“…So far, only a few analytical methods have been developed for the quantitative determination of Clo, mainly using chromatographic techniques, such as reversed phase high-performance liquid chromatography with UV detection (RPÀ HPLCÀ UV) [2], high-performance liquid chromatography with UV detection (HPLCÀ UV) [1], ultra-high-performance liquid chromatography with tandem mass spectrometry (UHPLCÀ MS/ MS) [3], gas chromatography-negative-ion chemical-ionization mass spectrometry (GCÀ NICIÀ MS) [4], liquid chromatography with matrix solid phase dispersion (MSPDÀ LC) [5], and liquid chromatography with reversed phase solid phase extraction (RPÀ SPEÀ LC) [6] in the following samples: beef [1], milk [1,3,5,6], egg [3], honey [3], muscle [3], cattle kidney [4], and commercial formulation [2]. However, electrochemical techniques can be successfully applied as a reliable tool in the quantitative analysis of pesticides [7][8][9], antibiotics [7,[10][11][12], drugs [13][14][15], and other substances requiring constant controlling [15][16][17][18][19]. To our knowledge, no previous electrochemical study of Clo have been reported in the literature so far.…”
